褐铁矿化

Through the search of main minerals under magnifying glass , it is definite that the silver mainly fine grained argentite and iodobromite in oxidized zone in Chagan silver deposit exists in limonite .

射线衍射分析，研究了银与铁，镁，锰，铅的相关性，以及镜下观察，确定了查干银矿床氧化带中银主要以硫化银及卤化银等独立矿物赋存于褐铁矿中，颗粒微细。

Under supergene process influencing, kaolinites invered dickites, siderite were been ferritization, part of carbonate mineral have been dissoluted producing calcite.

在表生作用的影响下，高岭石向地开石转化，菱铁矿褐铁矿化，部分碳酸盐矿物溶解生成方解石。

The authigenetic minerals' paragenetic sequence of paragenetic association III of outcrop sandstones is supergene leaching process-kaolinite-calcite- limonite.

露头砂岩的成岩共生组合III中自生矿物共生序列为：表生淋滤作用－高岭石地开石化－方解石-菱铁矿褐铁矿化。

Using the neutron activation analysis method, the author studied the trace element characteristics of silicified and limonitized quartz sandstones, diabases, limestones and pyrite in the Laozhaiwan gold deposit, and analyzed the relationships between the elements. The results show that the accompanying elements of Au in the study area can be used to guide the ore-prospecting work.

采用中子活化分析方法测试了老寨湾金矿区内的硅化褐铁矿化石英砂岩类、辉绿岩类、灰岩类和黄铁矿样品的微量元素特征，并利用元素地球化学研究方法对元素间的相关关系进行了分析，结果表明，在该地区可以利用金的伴生元素来指导找矿。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
