“…In general, the proposed scheme of mineral formation for the Cretaceous rocks of Southern Primorye [9] does not undergo any special changes. Therefore, it becomes possible to extend the information obtained to areas with a lesser degree of knowledge.…”

“…Clay and non-clay minerals in volcanogenic-sedimentary rock cement have previously been studied in detail: along the Southern Primorye [9,10,21], the Yamato Upland [22], the Terpeniya Peninsula (Sakhalin Island) [15,23], the Shikotan Island [23], and Vityaz Ridge (Kuril Arc) [23,24] (Figures 1-6, Figure S1, and Table S1 [25,26]).…”

“…Age zoning is expressed as follows: in the Lower Cretaceous rocks, chlorite-corrensite and chlorite-corrensite-laumontite associations dominate; in the Upper Cretaceous rocks, the role of the mixed-layer chlorite-smectite and mixed-layer illite-smectite formations with the appearance of analcime and stilbite is increased. The main conclusions made earlier [9] are that the chlorite-illite (illite-chlorite) association is found in all formations and that it cannot be determinative by itself. For the kaolinite-illite association, the time of formation can be established as Aptian-the beginning of the Early Albian-113-120 Ma (coal accumulation, the "Lipovetskoe" period, is noted in the Lipovetskaya Suite, Suchanskaya Series, and North Yamato Ridge).…”

In this study, clay and non-clay minerals in the cement of Cretaceous volcanogenic–sedimentary rocks from the bottom of the marginal seas of the north-western Pacific Ocean and adjacent areas were studied. Corrensite and mixed-layer chlorite–smectite, rectorite and mixed-layer illite–smectite, chlorite, swelling chlorite (?), illite, kaolinite, smectite (?), calcite, ankerite, barite, gypsum, epsomite, zeolites (laumontite, analcime, and stilbite), cristobalite, and quartz were determined. The following are the indicative properties: (a) minerals: corrensite and rectorite; (b) associations: corrensite–chlorite, corrensite–chlorite–laumontite, corrensite–epsomite–authigenic calcite, and quartz–illite. Such minerals indicate that the thickness of the accumulated sediments in the studied basins could reach three to five kilometers and that the temperature of their formation could be higher than 150 °C. Transformations in the process of diagenesis and epigenesis occur in two directions: smectite–rectorite–mica, with an excess of potassium, and smectite–corrensite–chlorite, with an excess of magnesium. The chlorite–corrensite association may indicate conditions favorable for seawater evaporation, and the presence of laumontite in the corrensite–chlorite association suggests a periodic supply of calcium to the sedimentation basin. The illite–kaolinite association is probably associated with coal accumulation in epicontinental conditions and a warm humid climate in nearby areas. Periods of sedimentation, possibly associated with global climate events, were identified: 113–120, 110–113, 105–110, 93–95, 72–83 and 61–72 Ma. The established time intervals and mineral associations can serve as benchmarks for stratigraphic constructions in reconstructing the physicochemical, climatic parameters, and conditions of Cretaceous volcanogenic–sedimentary strata accumulation.
