Abstract

Carbonate concretions in the region of Paramushir hydroacoustic anomalies are confined to the methane seep zones controlled by deep (tectonically weakened) bottom areas. Based on the structure, as well as chemical and mineral composition, the concretions can be classified as volcanosedimentary rock consisting of the vitro-, litho-, and crystalloclasts and buried microfauna cemented with the carbonate (aragonite) cement. The details and sequence of mineral formation of carbonate concretions are considered.

鄂霍次克海副湖水声异常区碳酸盐结块的组成及成因

副湖水声异常区域的碳酸盐结核局限于深部(构造弱化)底区控制的甲烷渗漏带。根据其结构、化学和矿物组成，可将其分类为火山沉积岩，由离体、岩屑和结晶碎屑组成，埋藏的微动物群以碳酸盐(文石)胶结物胶结。研究了碳酸盐结核矿物形成的细节和顺序。

期刊介绍： Lithology and Mineral Resources is an international peer reviewed journal that publishes articles on a wide range of problems related to the formation of sedimentary rocks and ores. Special attention is given to comparison of ancient sedimentary rock and ore formation with present-day processes. The major part of the journal is devoted to comparative analysis of sedimentary processes on the continents and in oceans, as well as the genetic aspects of the formation of sedimentary and hydrothermal–sedimentary mineral resources. The journal welcomes manuscripts from all countries in the English or Russian language.
