半深海沉积物-
含锰建造既可以是滨海&浅海沉积物，也可以是半深海一深海沉积物。硅质岩与含锰建造有直接成因联系，并为一些锑矿床及锡多金属矿床提供有利的成矿空间。
Mn-bearing formations are littoral-shallow sea se-diments , and may be bathyal-deep sea sediments as well . Because of the brittle fracture of silicalite can be provided a beneficial mineralization space for some antimony or Tin-multimetal deposits .
