鲕状构造

条带（条纹）状和豆鲕状构造是本矿床的主要矿石构造。

The major ores of this deposit have a banded ( streaky ), pisolitic or oolitic structure .

结果表明：矿石以鲕状构造为主，具有典型的同心环带结构。

The research results showed that the main ore structure is oolitic with a typical band structure of concentric rings .

文献中关于锰结核的同心环带结构、同心球粒状构造、鲕状构造、斑杂构造实际上是叠层石柱体的不同切面。

The concentric banded texture , concentric spherulitic , colitic and mottled structures reported in literature are actually different sections of the stromatolite columns .

主要矿物是高岭石，常见豆状、鲕状和碎屑状构造。

Their main mineral is kaolinite , usually in pisolitic , oolitic or clastic structure .
