Figure 83.—Clay fabric of highly oriented domains, core B-1 ( m). that numerous platy minerals were arranged at large angles to the general fissility of the shale. Gipson (1965) observed a similar fabric relationship during the study of fissility in shale. Strong preferred particle orientation but not perfect particle alignment is necessary to develop a relatively fissile sediment. Noteworthy also is the fact that these rather deeply buried submarine clays of porosity zone 5 are characterized by a preponderance of "thin," long, narrow voids which are produced by the particle-to-particle alignment and develop- ment of chains. The void geometry of the deeply buried clays is quite un- like the voids of the overlying high-porosity sediment, which is characterized by very irregular shape. In general descrip- tive terms, the voids of the shallow, high-porosity clays could be expressed by a length to width ratio which approaches a value of unity, whereas the lower, deeply buried clays would be characterized by a void geometry with the length to width ratio approaching infinity. Apparently a number of the obliquely trending particles and particles lying normal to the overall general preferred orientation of the clay fabric are associated with a few of the larger irregular shaped voids of the deeply buried clays. Clearly, despite the considerable strong degree of preferred clay particle orientation observed in these low-porosity clays, significant numbers of particles usually in the form of domains, deviate from the preferred general direction. This influences the overall fabric charac- teristics and thus produces few irregularly shaped voids and folding and bending of particles and chains. These character- istic features were not observed in the over
