    In:  Supplement to: Gutiérrez-Estrada, Mario; Salisbury, Matthew H (1983): Physical properties of sediments from the mouth of the Gulf of California, Leg 65, Deep Sea Drilling Project. In: Lewis, BTR; Robinson, P; et al. (eds.), Initial Reports of the Deep Sea Drilling Project (U.S. Govt. Printing Office), 65, 675-684, https://doi.org/10.2973/dsdp.proc.65.134.1983
    Publication Date: 2018-10-11
    Description: The physical properties of 138 unconsolidated hemipelagic silty clays and turbidites from the mouth of the Gulf of California were analyzed in order to determine their grain size, shear strength, compressional wave velocity, porosity, specific gravity, wet-bulk density, water content, void ratio, and degree of saturation. As at other Deep Sea Drilling Project (DSDP) sites, the wet-bulk density, sonic velocity, and shear strength tended to increase with depth while the porosity and water content decreased in response to increasing compaction. The grain size and clay fraction varied irregularly with depth. The wet-bulk density ranged from 1.34 to 2.58 g/cm**3, while, the shear strength and compressional wave velocity ranged from 0.03 to 1.05 tons/ft.**2 and 1.47 to 4.25 km/s, respectively. The porosity varied between 8 and 79%, while the water content ranged from 28.0 to 175.6%; most samples were effectively 100% saturated. The specific gravity ranged from 1.71 to 3.24 and showed a tendency to be directly related to the wet-bulk density and thus inversely related to porosity. The physical properties of the hemipelagic sediments and turbidites are noticeably different, and the properties of both were modified by diagenesis near the basement.

    In:  Supplement to: Gutiérrez-Estrada, Mario (1983): Grain-size distribution of sediments from the mouth of the Gulf of California, Deep Sea Drilling Project Leg 65. In: Lewis, BTR; Robinson, P; et al. (eds.), Initial Reports of the Deep Sea Drilling Project (U.S. Govt. Printing Office), 65, 451-469, https://doi.org/10.2973/dsdp.proc.65.119.1983
    Publication Date: 2019-02-13
    Description: The grain-size distribution of 223 unconsolidated sediment samples from four DSDP sites at the mouth of the Gulf of California was determined using sieve and pipette techniques. Shepard's (1954) and Inman's (1952) classification schemes were used for all samples. Most of the sediments are hemipelagic with minor turbidites of terrigenous origin. Sediment texture ranges from silty sand to silty clay. On the basis of grain-size parameters, the sediments can be divided into the following groups: (1) poorly to very poorly sorted coarse and medium sand; and (2) poorly to very poorly sorted fine to very fine sand and clay.

    In:  Supplement to: Gutiérrez-Estrada, Mario; Salisbury, Matthew H; Castro-del Rio, Alberto (1983): Atterberg limits of sediments from the mouth of the Gulf of California, Deep Sea Drilling Project Leg 65. In: Lewis, BTR; Robinson, P; et al. (eds.), Initial Reports of the Deep Sea Drilling Project (U.S. Govt. Printing Office), 65, 685-691, https://doi.org/10.2973/dsdp.proc.65.135.1983
    Publication Date: 2019-02-13
    Description: Atterberg limits have been determined for 32 unconsolidated sediment samples, ranging in composition from silty clay to sandy silt and recovered from four sites drilled at the mouth of the Gulf of California during DSDP Leg 65. The liquid limit of the samples ranged from 41.5% to 157.5%, and the plastic limit from 32.8% to 65.1%. The plasticity index ranged from 5.9% to 102.0%. In some samples, the water content was less than the liquid limit. The liquidity index averaged 76% while the flow and toughness indices averaged 35% and 2.18%, respectively. On the basis of these limits, the sediments analyzed can be classified as inorganic clays of high plasticity, organic clays of moderate to high plasticity, and diatomaceous sands, silts, and silty clays of low plasticity.

    In:  Supplement to: Gutiérrez-Estrada, Mario (1982): Grain-size distribution from the southeastern tip of Baja California and Guaymas Basin, Mexico, Deep Sea Drilling Project Leg 64. In: Curray, JR; Moore, DG; et al. (eds.), Initial Reports of the Deep Sea Drilling Project (U.S. Govt. Printing Office), 64, 543-551, https://doi.org/10.2973/dsdp.proc.64.109.1982
    Publication Date: 2019-02-13
    Description: Grain size of 139 unconsolidated sediment samples from seven DSDP sites in the Guaymas Basin and the southeastern tip of the Baja California Peninsula was determined by sieve and pipette techniques. Shepard (1954) classification and Inman (1952) parameters correlation were used for all samples. Sediment texture ranged from sand to silty clay. On the basis of grain-size parameter, the sediments can be divided into three broad groups: (1) very fine sands and coarse silts; (2) medium- to very fine silts; and (3) clays and coarse silts.
