Россия, Амурская область, врез автодороги Хабаровск-Чита. Урильская свита. Слюдяные сланцы с тонкими прослойками графитистых сланцев, мощностью 550 м. Сланцы обладают лепидогранобластовой и гранолепидобластовой структурами и состоят нз кварца (30—65%), альбита (13—60%), биотита (5—35%), графита (0—32%), хлорита (0—25%), мусковита (0—20%), реже граната, амфибола, микроклина. Акцессорные минералы представлены сфеном и апатитом. В зависимости от количественного соотношения этих минералов выделяются двуслюдяные-альбит-кварцевые, хлорит-альбит-кварцевые, графитистые и другие сланцы.

Russia, Subpolar Ural, Kozhim river valley. White, light gray marbled limestones. Include microlayers of quartz-mica composition, the content of quartz grains in them sometimes reaches 30–35%. Under the microscope of the rock, a granoblastic structure with relics of an uneven-grained - blastopsammite and blastoaleurite is found; layered, banded texture and consist of a calcite heterogeneous aggregate (70–99%) with intercalations of quartz grains (up to 25%) and microlayers of carbonaceous-chlorite-sericite, muscovite-chlorite composition.
Russia, Magadan region, left side of the Duck river. Quartz-albite diorite porphyrite with quartz-albite veins. These are the famous Ducks dykes. Dyke №7. The dyke is a slab-like body with a capacity of 0.5 m in the East to 3.5 m in the West, accompanied by apophyses that run parallel to the sedimentary rocks (lower Jurassic siltstone). It is traced to a depth of 250 meters. Xenoliths are rare. Sometimes there are intersecting, until the disappearance of dykes.
Russia, Khabarovsk Territory, Yagdynya river. Biotite Granites. Form an massif of 850 square kilometers. Consist: oligolclase - 24-32%, microcline - 24-45%, quartz - 15-29%, biotite - 4-11%. Plagioclase forms sericite and albite (auto-metasomatism). Chlorite is formed by biotite. Accessory: sphene, zircon, apatite. Definitions of absolute age (K): 207, 230, 235 million years. Upper Triassic.
