“…When analyzing the clay mineral assemblages of Cretaceous rock cement in the transition zone from the Asian continent to the Pacific Ocean, the following six periods in sedimentation are distinguished, possibly associated with world global climatic events: 113-120, 110-113, 105-110, 93-95, 72-83, and 61-72 Ma. The first three periods are confirmed by absolute data [38], but the others require clarification.…”

“…The latest data [38] for the south of Primorye Region give two absolute ages for the Early Cretaceous period of coal accumulation-118 ± 1.4 and 109 ± 1 Ma for the Lipovetskaya (Nikanskaya Series) and Frentsevskaya (Suchanskaya Series) Suites, respectively. Now, it is possible to specify the time of existence of the kaolinite-illite association (the period of coal accumulation or the first "Lipovetskoe" event); the time is older than 118 ± 1.4 million years and in the region of 109 million years.…”

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.

“…Выше по разрезу следуют слои песчаников, конгломератов, алевролитов, туффитов и черных сланцев с остатками рыб, пресноводных моллюсков и растений. Совсем недавно из слоев туффитов выделены остаточные цирконы, по которым получены возрастные датировки в 109±1 млн лет (Golovneva et al 2021), что соответствует границе раннего и среднего альба согласно действующей общей стратиграфической шкале России (Стратиграфический кодекс… 2019). Френцевскую свиту перекрывает коркинская серия, в которой растительных остатков мало, а возраст ее оценивается как поздний альб -ранний сеноман (Volynets 2005).…”

A taxonomic study of Albian ferns from the Partizansk Coal Basin of Primorsky Krai was carried out. The Albian Age was an important stratigraphic milestone, when the Early Cretaceous flora changed to the Late Cretaceous flora. It was revealed that typical Mesozoic Onychiopsis predominated in taphocenoses, and representatives of young and evolutionarily advanced taxa Asplenium, Birisia appeared. The taxonomic composition of ferns in the Albian taphocenoses was almost constant from north to south. The vegetation of the Partizansk Basin occupied the coastal plain during Albian time, which was confirmed by the remains of marine and freshwater mollusks, phytofossils, as well as fish.
