It is a megadepression evolving from a Mesozoic back-arc paraforeland basin to a Cenozoic intermountain basin, and filled with large sets of argillaceous rock, calcareous mudstone, carbonate rock and clastic rock of saliniferous-semisaliniferous environment under the semidry climate of inland lakes which form a set of giant-thick hydrocarbon source rock with two periods of hydrocarbon-expulsion peaks, two types of reservoir series as well as special capping and migration conditions.

是一个由中生代弧后准前陆盆地向新生代山间盆地发展演化的一个大型坳陷。充填了内陆湖泊半干旱气候下咸化环境－半咸化环境的大套泥质岩，含钙质泥岩及碳酸盐岩和碎屑岩。形成一套巨厚的具两期排烃高峰的烃源岩，两种类型的储集岩系、特殊的盖层条件及运移条件。

Iron carbonate, FeCO3, as is siderite.

与菱铁矿一样，是碳酸亚铁FeCO3。

The result makes clear, can be restrained on certain level by starch but the siderite with weaker inhibition in hematite and quartz exterior adsorption overspreads a lid, it is the main reason that causes Dong Anshan to contain carbonate iron ore to turn over floatation difficulty.

结果表明，可在一定程度上受到淀粉抑制但抑制功能较弱的菱铁矿在赤铁矿和石英表面的吸附罩盖，是引起东鞍山含碳酸盐铁矿石反浮选困难的主要原因。

Accordingly, want to realize Dong Anshan to contain the effective depart of content of the iron ore in carbonate iron ore and quartz, if where,the key is before turning over floatation, go out siderite depart beforehand, or the floatation drug that find can effective activation or restrains siderite.

因此，要实现东鞍山含碳酸盐铁矿石中铁矿物和石英的有效分离，关键是如何在反浮选之前预先将菱铁矿分离出去，或找到能有效活化或抑制菱铁矿的浮选药剂。

The main component of cement is carbonate,a small amount of siliceous cement and iron cement.

胶结物的组分主要以碳酸盐胶结物为主，另有硅质胶结和少量铁质胶结。

The mineralization of gold and silver is zoned and closely related to silicification of carbonate and clastic rocks, so siliceous ore dominates in the deposit.

矿化温度主要在300～170 C之间，成矿流体的主要成分为K~-、Na~-、Ca~(2+)、Mg~(2+)、Cl~。金属配合物的分配计算显示，金在成矿热液中主要以疏氢配合物迁移，而银、铁、铅、锌则以氯配合物为主，铁、铅、锌在成矿后期的中性-弱碱性环境下可转变为羟基和硫氢配合物。

The catalytic effect of sodium carbonate on their thermal behavior was also investigated.

同时研究了碳酸钠对这三种木材热解的催化效应。
