    Notes: [Auszug] The first stages of planetary accretion in the early Solar System produced small bodies, or 'planetesimals', of rock and ice. Most of these first-born were swallowed up by the present-day planets as they grew, but some survived as asteroids, orbiting between Mars and Jupiter where no large planet ...

    Notes: [Auszug] IN the past decade, hypotheses to explain the origin of the solar system have been advanced which are consistent with almost all that is known about the nature of the universe and about the behaviour of matter. Postulated ad hoc events have been minimized. Perhaps there is reason for believing that ...

    Boulder 1, Station 2, Apollo 17: Petrology and petrogenesis (1975)

    Notes: Abstract Boulder 1, Station 2, Apollo 17 is a stratified boulder containing dark clasts and dark-rimmed light clasts set in a light-gray friable matrix. The gray to black clasts (GCBx and BCBx) are multigenerational, competent, high-grade metamorphic, and partially melted breccias. They contain a diverse suite of lithic clasts which are mainly ANT varieties, but include granites, basaltic-textured olivine basalts, troctolitic and spinel troctolitic basalts, and unusual lithologies such as KREEP norite, ilmenite (KREEP) microgabbro, and the Civet Cat norite, which is believed to be a plutonic differentiate. The GCBxs and BCBxs are variable in composition, averaging a moderately KREEPy olivine norite. The matrix consists of mineral fragments derived from the observed lithologies plus variable amounts of a component, unobserved as a clast-type, that approximates a KREEP basalt in composition, as well as mineral fragments of unknown derivation. The high-temperature GCBxs cooled substantially before their incorporation into the friable matrix of Boulder 1. The light friable matrix (LFBx) is texturally distinct from the competent breccia clasts and, apart from the abundant ANT clasts, contains clasts of a KREEPy basalt that is not observed in the competent breccias. The LFBx lacks such lithologies as the granites and the Civet Cat norite observed in the competent breccias and in detail is a distinct chemical as well as textural entity. We interpret the LFBx matrix as Serenitatis ejecta deposited in the South Massif, and the GCBx clasts as remnants of an ejecta blanket produced by an earlier impact. The source terrain for the Serenitatis impact consisted of the competent breccias, crustal ANT lithologies, and the KREEPy basalts, attesting to substantial lunar activity prior to the impact. The age of the older breccias suggests that the Serenitatis event is younger than 4.01±0.03 b.y.

    The nature and origin of Boulder 1, Station 2, Apollo 17 (1975)

    Notes: Abstract The Boulder 1 breccias are similar in composition to other Taurus-Littrow massif samples and therefore probably derived from the same source, undoubtedly the Serenitatis basin. However, they are substantially different in texture from other Apollo 17 massif rocks, indeed are very nearly unique among the rocks returned by all Apollo missions. The boulder is set apart by its content of dark, rounded inclusions or bombs, up to several tens of centimeters in dimension, consisting largely of very fine, angular, mineral debris, welded together by a lesser amount of extremely fine-grained material that appears to be devitrified glass. To account for these uncommon structures, a phase of the basinforming impact event is sought that would produce relatively small amounts of debris and deposit them on or near the basin rim. It is suggested that the components of the boulder might represent very early, high angle ejecta from the Serenitatis event, and that the dark breccia inclusions are accretional structures formed from a cloud of hot mineral debris, melt droplets, and vapor that was ejected at high angles from the impact point soon after penetration of the Serenitatis meteoroid. This small amount of early high-angle ejecta would have remained in ballistic trajectories while the main phase of crater excavation deposited much larger amounts of deeper-derived debris and melt-rock on the rim of the basin, after which the early ejecta was deposited as a cooler (∼450°C) stratum on top. The matrix of this breccia gained its modest degree of coherency by thermal sintering as the capping stratum cooled. The boulder is a fragment of this layer, broken out and rolled to the foot of the South Massif ⩽ 55 m.y. ago.

    Bombardment as a cause of the lunar asymmetry (1973)
    Springer

    Notes: Abstract A comparison of the lunar frontside gravity field with topography indicates that low-density (∼ 2.9 g cm−3) types of rock form a surface layer or crust of variable thickness: 40-60 km beneath terrae; 20-40 km beneath non-mascon maria; 0-20 km beneath mascon maria. The observed offset between lunar centers of mass and figure is consistent with farside crustal thicknesses of 40-50 km, similar to frontside terra thicknesses. The Moon is asymmetric in crustal thickness, and also in the distribution of maria and gamma radioactivity. Early bombardment of the Moon by planetesimals, in both heliocentric and geocentric orbits, is examined as a possible cause of the asymmetries. The presence of a massive companion (Earth) causes a spin-orbit coupled Moon to be bombarded non-uniformly. The most pronounced local concentration of impacts would have occurred on the west limb of the Moon, when it orbited close to the Earth, if low-eccentricity heliocentric planetesimals were still abundant in the solar system at that time. A very intense bombardment of this type could have redistributed crustal material on the Moon, thinning the west limb crust appreciably. This would have caused a change in position of the principal axes of inertia, and a reorientation of the spin-orbit coupled Moon such that the thinnest portion of its crust turned toward one of the poles. Erupting lavas would have preferentially flooded such a thin-crusted, low-lying area. This would have caused another readjustment of principal moments, and a reorientation of the Moon such that the mare areas tipped toward the equator. The north-south and nearside-farside asymmetries of mare distribution on the present Moon can be understood in terms of such a history.

    Notes: [Auszug] METEORITES are complex, ancient, enigmatic rock fragments from somewhere beyond Mars. They were formed at the same time as the Solar System, and they retain a cryptic record of the events of that time. In the 30 years since Harold Urey and Harrison Brown unleashed the techniques and concepts of ...

    Notes: Abstract Radiometric dating shows that the earliest steps in forming the substance of meteorites and assembling it into planetesimals occurred in a very short interval of time, 1–2 Ma. This study shows that rapid formation is also dictated by the need to use short-lived 26Al (half-life T 1/2=0.74 Ma) as a heat source to metamorphose and in some cases melt the meteorite parent bodies after they accreted. The earliest events in solar system history dated by cosmochemists, formation at high temperatures of the Ca,Al-rich inclusions that occur in chondritic meteorites, probably occurred during the most energetic stage of protosolar disk evolution, as the protosun neared its present mass and infall drew to a close.
