In this study, clay and non-clay minerals in the cement of Cretaceous volcanogenic–sedimentary rocks from bottom marginal seas north-western Pacific Ocean adjacent areas were studied. Corrensite mixed-layer chlorite–smectite, rectorite illite–smectite, chlorite, swelling chlorite (?), illite, kaolinite, smectite calcite, ankerite, barite, gypsum, epsomite, zeolites (laumontite, analcime, stilbi...
The Pelona, Orocopia, and Rand Schists and the schists of Portal Ridge and Sierra de Salinas constitute a high–pressure-temperature terrane that was accreted beneath North American basement in Late Cretaceous–earliest Tertiary time. The schists crop out in a belt extending from the southern Coast Ranges through the Mojave Desert, central Transverse Ranges, southeastern California, and southwest...
The Qotur metamorphic complex consists of metabasites, gneisses, marbles and calc-silicates as well as serpentinites which is cropped out at the west border of West Azerbaijan and Turkey. The amphibolites from the Qotur metamorphic complex can be classified as two types of ortho- and para-amphibolites. Minerals in this ortho-amphibolite are hornblende, plagioclase, zircon, titanite, and opaque ...
Chemical analyses of chlorite flakes, as a product of alteration of biotite in the Eocene granitoid rocks of Naghade and Pasveh intrusions have been accomplished by electron microprobe for major elements. Based on 53 point analyses of chlorites from 13 rock samples, their mean structural formula recalculations display that Si cation numbers are less than 5.97 atoms per formula unit (apfu), and ...
