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.
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.
