Geology Of Kazakhstan
The geology of Kazakhstan includes extensive basement rocks from the Precambrian and widespread Paleozoic rocks, as well as sediments formed in rift basins during the Mesozoic. Geologic history, stratigraphy and tectonics Archean rocks of the Zerenda Group, including schist, diamond-bearing gneiss, eclogite and marble are found in the Kokchetav Massif in the Kazakh Uplands. However, geologists have disagreed on dating with some indicating dates in the Middle Cambrian or Archean through Paleoproterozoic. Early Proterozoic rocks are better defined and include phyllite, schist, quartzite, porphyroids, porphyritoids, marble and jaspellite, intruded by 1.8 billion year old granite gneiss and 1.7 billion year old granosyenite. The Paleoproterozoic sequence is 14 kilometers thick. In the Jeltau Mountains, the basement is made up gneiss, schist, marble, amphibolite and eclogite. Migmatized gneiss, amphibolite and quartzite are found in the Mugodzhar area. Precambrian rocks a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sedges
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus ''Carex'' with over 2,000 species. These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be found growing in almost all environments, many are associated with wetlands, or with poor soils. Ecological communities dominated by sedges are known as sedgelands or sedge meadows. Some species superficially resemble the closely related rushes and the more distantly related grasses. Features distinguishing members of the sedge family from grasses or rushes are stems with triangular cross-sections (with occasional exceptions, a notable example being the tule which has a round cross-section) and leaves that are spirally arranged in three ranks. In comparison, gra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Takir (soil)
Takir (takyr) (russian: такыр, originally from Kazakh or another Turkic language) meaning "smooth, even, or bare", is a type of relief occurring in the deserts of Central Asia, similar to a salt flat in the southwestern United States. A takyr is usually formed in a shallow depressed area with a heavy clay soil, which is submerged by water after seasonal rains. After the water evaporates, a dried crust with fissures forms on the surface. The crust is often colonized by filamentous cyanobacteria. In the southwestern U.S. "takyrs" are known as "playas" or "salt flats", in Arab countries as "sabkha".
