Miscellaneous Features in Argillaceous Rocks,emical and microfabric conditions. Rickard indicates the spheroidal shape may be due to pseudomorphism of a pre-existing spherical body. It may represent replacement of an immiscible organic liquid globule by iron sulfide or infilling by microcrystalline pyrite of spherical gaseous vacuoles or even

Formation of Shale by Compaction of Flocculated Clay--A Model,action (mechanical rearrangement of particles) in shale formation. It is commonly agreed that most clay-rich sediment settles out in sea water as aggregates or floccules. The “flocculated model” (see section on PREFERRED PARTICLE ORIENTATION IN SHALE) shows how parallel particles result from an orig

Fabrics of Some Hydrocarbon Source Rocks and Oil Shales, or carbonate sediment that in its natural setting has generated and released enough hydrocarbons to form a commercial accumulation of oil or gas. Studies of source rocks have emphasized the organic fraction of the sediments and there is very little published information on the inorganic fraction. A

Fabric of Geopressured Shale,ressuring. Our investigation of geopressured shales is very preliminary so we hope that the examples presented here will stimulate additional research. The term “geopressure” is used to describe pore fluid pressures which are greater than hydrostatic pressure (the pressure equal to that of a column

Composition of Argillaceous Rocks,laceous rocks used in this study. Also listed are ranges and average values of Total Organic Carbon (TOC). The data in Table 1 are compiled from individual rock descriptions in the text, in addition to other analyses of rocks not given with individual rock descriptions (Table 2).
