    Description: Die untersuchten, feinkörnig-konglomeratischen, mäßig gut sortierten, lithischen Arenite, bilden zusammen mit Siltsteinen und untergeordnet Tonschiefern die Sao Khua Formation, die als Speichergestein der Uran-Vererzung Phu Wiang I in einem fluviatil-beherrschten Deltakomplex mit deutlich marinen Einflüssen im Zeitraum Ober-Jura bis Unter-Kreide sedimentiert wurde. Die in den Areniten der Sao Khua Formation aufgearbeiteten Klasten und der detritische Mineral bestand deuten auf sauer bis intermediäre Plutonite und Vulkanite, Phyllite, Quarzite und Cherts als Liefergesteine. Erosionsgebiete dieser Gesteinsserien sind wegen der rekonstruierten, unimodalen, hauptsächlich NE/SW verlaufenden Paläoströmungsrichtung in pratriassischen Formationen, nordöstlich des Untersuchungsgebietes, zu suchen. Zusammen mit diesen sind möglicherweise äolisch nach E verfrachtete Vulkanite, des westlich von Si Chiang Mai gelegenen Vulkanitgürtels, umgelagert und im Deltabereich sedimentiert worden. Die linsenförmige, penekonkordante Uran-Mineralisation ist an mittel- bis grobkörnige, teilweise konglomeratische Bereiche, des als “channelsequenz" interpretierten Sandsteins gebunden, die feinverteiltes, inkohltes Pflanzenmaterial enthalten und im Hangenden einer für (perkolierende) Porenwässer impermeablen Barriere aus feinkörnigen Sandsteinen, Siltsteinen und Tonschiefern liegen.
    Description: Fine grained to conglomeratic, moderateley well-sorted, lithic arenites combine with siltstones and minor amounts of shale to make the Sao Khua formation. The latter was deposited during the Upper Jurassic and Lower Cretaceous in a delta donimated by fluvial distributary channels but with distinct marine features and is the host roch for the uranium mineralization. The clasts and the detritic minerals of the arenites of the Sao Khua Formation indicate that acid to intermediate plutonios and volcanics, phyllites, quarzites and cherts were the source rocks. Possibly volcanics from the volcanic arc, situated to the west of Si Chiang Mai, were aeolianly transported to the east and after their first deposition carried together with the above cited detrital mineral assemblage by fluvial action into the delta area. The lenticular, peneconcordant uranium mineralization is restricted to these medium to coarse grained, partly conglomeratic intervals of the sandstone which together have been interpreted as channel - sequences. These intervals contain finely distributed carbonaceous matter of plant origin and are situated above a barrier. The latter is made up of fine-grained sandstone, siltstone and shale, which connot be permeated by (percolating) pore-water-solutions.

    Description: Die Magmatite des Indosinia-Orogens in NE-Thailand wurden auf Grund von petrographischen und petrochemischen Untersuchungen durch die Einführung geochemischer Indizes nach folgenden Gesteinstypen und Sippen klassifiziert, sowie den entsprechenden magmatischen Phasen im orogenen Zyklus zugerechnet. - Alkali-Rhyolithe, die als Ignimbrite und Tuffe auftreten, sowie Dacite, die der Kalk-Alkali-Reihe angehören (frühe Phase des finalen Magmatismus) im Pak Chom-Si Chiang Mai Gebiet und im Loei-Chum Phae Gebiet. Letztere zeigen auch eine Tendenz zu einer höheren Alkalini tat (finaler Magmatismus) im Saraburi -Gebiet bzw. Loei-Tha Li Gebiet. - Andesite, die als Tuffe und Agglomerate vorliegen und der Kalk-Alkali-Reihe mit einem mittelstark pazifischen Charakter angehören (früher subsequenter Magmatismus) im Chum Phae-Lom Sak Gebiet. - Lenco-Basalte mit einem ophitischen Gefüge, die sowohl der Kalk- Alkali -Reihe (früher subsequenter Magnetismus) im Chiang Khan Gebiet, als auch einer Obergangsphase zur Alkali-Reihe (finaler Magnetismus) im Petchabun und Saraburi Gebiet zuzurechnen sind. - Granite-Monzonite, die der Kalk-Alkali-Reihe angehören (synorogener Magnetismus) im Loei-Chiang Khan Gebiet. Petrographische und geochemische Untersuchungsergebnisse, sowie paläogeographische und quantitative Voraussetzungen zeichnen die alkali-rhyolithischen Ignimbrite und Tuffe des Pak Chom-Si Chiang Mai Gebietes als potentielle Uran-Lieferanten aus. Folgende Untersuchungsergebnisse können als Begründung herangezogen werden: - Die ober-triassischen bis unter-jurassischen Ignimbrite und Tuffe des Pak Chom-Si Chiang Mai Gebietes sind dicht verschweißt und ihre Grundmasse liegt zu einem großen Teil in einem vollständig devitrifizierten Zustand vor, im Gegensatz zu den der Saraburi und Loei-Tha Li Gebiete, in denen die holohyalinen Anteile in der Grundmasse z.T. überwiegen. -Die Alkali-Rhyol ithe des Pak Chom-Si Chiang Mai Gebietes sind am höchsten differenziert, wie dem numerischen +Differentiationsindex (bis 16,65) zu entnehmen ist. - Sie zeigen die größten Gehalte an lithophilen Spurenelementen (Ba: 415 - 969 ppm; Rb: 109 - 213 ppm; Sr: 35 - 124 ppm; Zr: 77 - 209 ppm;) innerhalb vergleichbarer Differentiationsgrade der Alkali-Rhyolithe des Loei-Tha Li und Saraburi Gebietes. - Die Uran- und Lithium-Gehalte sind dagegen ungewöhnlich niedrig und liegen im Bereich von 2,09 - 3,6 ppm U bei einem Th/U-Verhältnis von 2,2 - 8,5 und 2,5 - 61,3 ppm Li (mit einem Mittelwert von 15,60 ppm Li), im Gegensatz zu den U- und Li-Gehalten des Loei-Tha Li Gebietes (U = 3,1 - 7 ppm; Th/U = 1 - 2; Li = 6,0 - 210,0 ppm, mit einem Mittelwert von 79 ppm Li) und des Saraburi Gebietes (U = 3,6 - 5 ppm; Th/U = 3,2 - 4,0; Li = 10,90 - 43,00 ppm, mit einem Mittelwert von 27,9 ppm Li). - Der xOxidationsgrad (0x0 = 0,51 - 0,99) ist mit dem U-Gehalt negativ korrelierbar im Gegensatz zu dem der Alkali-Rhyolithe in den anderen Gebieten. Zu ähnlichen, sich scheinbar widersprechenden, Untersuchungsergebnissen in Ignimbriten und Tuffen gelangten ROSHOLT et al. (1969), SCHATKOV et al. (1970) und ZIELINSKI (1978). Die geringen U-Gehalte werden auf die größere Mobilationsbereitschaft der leichtflüchtigen Elemente (Uran, Lithium, Fluor und Chlor) und deren Verbindungen während des Devitrifikationsprozesses im Zuge der langen Abkühlungszeit mächtiger Ignimbrit- und Tuffdecken zurückgeführt. Das in mobiler Phase vorliegende Uran (U6+) kann entweder supergene Anreicherungen innerhalb der Ignimbrit-Tuff-Decken bilden, die bei einer einsetzenden Erosion in Form von Uran-angereichertem Detritus weiter transportiert werden, oder direkt in migrierende Grundwässer gelangen. Der so eingetretene Verlust von Uran kann bei den Pak Chom-Si Chiang Mai alkali-rhyolitischen Ignimbriten und Tuffen mit einer Größenordnung von 46 - 52 % angegeben werden. Zu den von SCHATKOV (1970) ermittelten prospektionssignifikanten Faktoren (Devitrifikationsgrad, Th/U und 0x0 in Abhängigkeit vom U-Gehalt) kann als ergänzende Prospektionshilfe für supergene U-Anreicherungen in Ignimbriten bzw. Tuffen die geochemische Inkongruenz des U-Li-Gehaltes und des Differentiationsindex erwähnt werden. Im Gegensatz zur normalerweise positiven Korrelation von Oxidationsgrad, Thorium-Uran-Lithium-Gehalt und Differentiationsindex nimmt bei den Pak Chom-Si Chiang Mai Ignimbriten und Tuffen der U-Li -Gehalt bei den höchsten Differentiationsgraden ab. +Differentiationsindex: 1/3 Si + K - Ca - Mg xOxidationsgrad (0x0) : Fe3+ / Fe2+ + Fe3+ + Mn
    Description: According to the results of petrographic and petrochemical investigations using geochemical indices, the magmatites of the Indos inia-orogeny in NE-Thailand have been classified in the following rock types and associations as well as attributed to the corresponding magmatic phases of the orogenic cycles. - alkalirhyolithic ignimbrites and tuffs as well as dacites belonging to the calc-alkaline series (early phase of the final magmatism) in the Pak Chom-Si Chiang Mai and Loei-Chum Phae area. Both rock types tend toward alkalinity (final magmatism) in the Saraburi, that is Loei-Tha Li area. - andesitic tuff and agglomerates »belonging to the calc-alkaline series with a medium to strong Pacific character (early subsequent magmatism) in the Chum Phae-Lom Sak area. - leuco-basalts with an ophitic texture, belonging partly to the calc-alkaline series (early subsequent magmatism) in the Chiang Khan area and partly to a transitions phase of the alkaline series (final magmatism) in the Pete ha bun and Saraburi province. - granite-monzonites, belonging to the calc-alkaline series (synorogenic magmatism) in the Loei-Chiang Khan area. The petrographic and goechemical investigations, as well as the palaeographic and quantitative conditions suggest that the alkalirhyol ithic ignimbrites and tuffs of the Pak Chom-Si Chiang Mai area are the potential uranium source-rocks in the area under investigation. The following results support this assuption: - the Upper Triassic - Lower Jurassic alkalirhyolithes of the Pak Chom-Si Chiang Mai area consist of densely welded and nearly completely devitrified ignimbrites and tuffs, in contrast to those of the Saraburi and Loei-Tha Li areas, which show a high amount of holohyaline groundmass. - the alkalirhyolithes of the Pak Chom-Si Chiang Mai area are the most differentiated of all those investigated, as shown by the high numerical differentiationindex+ (16,65). - the content of lithophile trace elements (Ba: 415 - 969 ppm; Rb: 109 - 213 ppm; Sr: 35 - 124 ppm; Zr: 77 - 209 ppm;) is higher than that of the alkalirhyolithes exhibiting the same degree of the differentiation

    Description: Miocene paleoceanographic evolution exhibits major changes resulting from the opening and closing of passages, the subsequent changes in oceanic circulation, and development of major Antarctic glaciation. The consequences and timing of these events can be observed in variations in the distribution of deep-sea hiatuses, sedimentation patterns, and biogeographic distribution of planktic organisms. The opening of the Drake Passage in the latest Oligocene to early Miocene (25-20 Ma) resulted in the establishment of the deep circumpolar current, which led to thermal isolation of Antarctica and increased global cooling. This development was associated with a major turnover in planktic organisms, resulting in the evolution of Neogene assemblages and the eventual extinction of Paleogene assemblages. The erosive patterns of two widespread hiatuses (PH, 23.0-22.5 Ma; and NH 1, 20-18 Ma) indicate that a deep circumequatorial circulation existed at this time, characterized by a broad band of carbonate-ooze deposition. Siliceous sedimentation was restricted to the North Atlantic and a narrow band around Antarctica. A major reorganization in deep-sea sedimentation and hiatus distribution patterns occurred near the early/middle Miocene boundary, apparently resulting from changes in oceanic circulation. Beginning at this time, deep-sea erosion occurred throughout the Caribbean (hiatus NH 2, 16-15 Ma), suggesting disruption of the deep circumequatorial circulation and northward deflection of deep currents, and/or intensification of the Gulf Stream. Sediment distribution patterns changed dramatically with the sudden appearance of siliceous-ooze deposition in the marginal and east equatorial North Pacific by 16.0 to 15.5 Ma, coincident with the decline of siliceous sedimentation in the North Atlantic. This silica switch may have been caused by the introduction of Norwegian Overflow Water into the North Atlantic acting as a barrier to outcropping of silica-rich Antarctic Bottom Water. The main aspects of the present oceanic circulation system and sediment distribution pattern were established by 13.5 to 12.5 Ma (hiatus NH 3), coincident with the establishment of a major East Antarctic ice cap. Antarctic glaciation resulted in a broadening belt of siliceous-ooze deposition around Antarctica, increased siliceous sedimentation in the marginal and east equatorial North Pacific and Indian Oceans, and further northward restriction of siliceous sediments in the North Atlantic. Periodic cool climatic events were accompanied by lower eustatic sea levels and widespread deep-sea erosion at 12 to 11 Ma (NH 4), 10 to 9 Ma (NH 5), 7.5 to 6.2 Ma (NH 6), and 5.2 to 4.7 Ma (NH 7).

    In:  Supplement to: Leinen, Margaret W (1981): Metal-rich basal sediments from northeastern Pacific Deep Sea Drilling Project Sites. In: Yeats, RS; Haq, BU; et al. (eds.), Initial Reports of the Deep Sea Drilling Project (U.S. Govt. Printing Office), 63, 667-676, https://doi.org/10.2973/dsdp.proc.63.123.1981

    Description: Sediments from immediately above basalt basement and from between sections of basalt recovered from Deep Sea Drilling Project Legs 5 and 63 were analyzed by atomic absorption spectroscopy for Mg, Al, Si, Ca, Mn, Fe, Co, Ni, Cu, Zn, and Ba. All of these sediments showed enrichment in Fe and Mn over values typical of detritus supplied to the northeastern Pacific Ocean. X-ray diffractometry and differential chemical leaching indicate that up to 50% of the sediment, by weight, is in amorphous phases and that these phases are rich in Mn, Co, Cu, Ni, and Zn. Multivariate statistical analysis and normative partitioning of the chemical data indicate that much of the excess Fe and other transition elements in the sediment originate from hydrothermal sources.
