The role of biogeochemical barriers as areas of an estuary with dramatically changing gradients of water characteristics in trace metal (TM) migration in the river-sea system, and the influence of physical, chemical, biological factors and corresponding barrier zones on the transport of TM in estuaries is considered. The effects of surface water pH (the Yuriev River — the Okhotsk Sea estuarine system), salinity and biological productivity (the Razdolnaya River — the Japan Sea estuarine system) on the behavior of some metals are demonstrated as the examples of different types of estuarine biogeochemical barriers. 相似文献

Summary Considering the effects of causal mechanics on geophysical problems enables us to explain a number of phenomena, which cannot
be explained from conventional positions. This paper shows that the introduction of the force of causality in a simple barotropic
hydrodynamic model of weather forecasts results in the outcomes, which, on the one hand, can not be described from the positions
of classical hydro-thermodynamics, whilst on the other hand, exist in nature. 相似文献

The ore-bearing dikes widespread in the Yana-Kolyma metallogenic belt vary in composition from granite porphyry to lamprophyres, gabbromonzonite, and dolerite. The dikes make up suites tens of kilometers in extent and up to 8–10 km wide or fields a few thousand square kilometers in area. Previously, the ore mineralization was traditionally referred to the gold-quartz type superimposed on dikes. However, isotopic and thermobarogeochemical data indicate that the mineralization is close to an intrusion-related gold deposit. A deep magma chamber could have been a source of sulfur in sulfides from beresites and quartz veins hosted in the Kolyma dikes. The deposits considered in the paper are permissive for large economic reserves with low and medium Au grades. 相似文献

Original data on the ore composition are obtained by studying samples from mining workings. In terms of mineral composition, gold-productive veinlets are subdivided into three types: sulfide–quartz, sulfide–carbonate–quartz, and sulfide. The wall-rock metasomatites and typomorphic features of the minerals are studied and the genetic problems of the ores and deposit are discussed. It is established that the Malinovka deposit is ascribed to the gold–tourmaline type (gold–quartz formation), which is identified for the first time in Primorye. In terms of many parameters, the ores of this type are close to those of the large deposits from the Transbaikalian and Amur regions (Klyuchevsky, Kariy, Kirov, Darasun, and others), which are genetically related to granitoid magmatism. 相似文献

The paper reports the mineralogical and geochemical features of the Kysylga gold deposit located in the hornfelsed Norian sedimentary rocks and classified with low-sulfide gold–quartz type of deposits typical of the Verkhoyansk–Kolyma metallogenic province. Detailed typomorphic study of the major minerals (quartz, arsenopyrite, and gold) of the ore veins shows that the deposit is assigned to the gold–silver type. Mineralogical and geochemical data substantiate this conclusion. 相似文献
