Huangshaping Pb-Zn deposit originated from high-middle temperature solutions. Structures developed in area consist of NNE-striking folds, N-S and nearly E-W faults system. There are Upper Devonian and Lower Carboniferous outcropped, and the Shidongzi Formation limestone of the later is the main host rock. Ore body has various shapes with a great number of minerals and complex chemical compositions.

黄沙坪铅锌矿床属高中温热液成因的金属矿床，矿区内构造主要包括北北东向为主的褶皱和南北向、近东西向为主的断裂构造系统；出露地层主要有上泥盆统和下石炭统，其中下石炭统石磴子组灰岩为主要赋矿围岩；区内矿体形态多样，矿石矿物种类繁多，化学成分复杂。

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。

Considering the three principles of the plant indicator for mineral exploration,namely certainty,sensitivity and feasibility,this paper evaluates comprehensively the indicating functions of the eight plants,on the basis of some quantitative indexes such as the relation coefficient between plant ash and ore-forming element,concentration coefficient,etc.

植物找矿法包括地质植物法和植物灰分法，前者为该方法一个古老的形态学分支，国内外均应用较早[1] [2 ] [3] ；后者为该方法的地球化学分支，由于生产实践的需要和科学技术的发展，已从实践上理论上得到肯定，并日益受到重视，特别是在盲矿体的找寻工作中发挥了重要作用。

One of coal, iron, gypsum, pyrite, magnesite, kyanite, barite, graphite, china clay ore, copper, cobalt, molybdenum, such as higher levels of mineral exploration, and industrial dolomite, limestone, refractory clay, bauxite and other mineral deposits at the end of the exploration degree.

其中煤、铁、石膏、硫铁矿、菱镁矿、蓝晶石、重晶石、石墨、瓷土矿、铜、钴、钼等矿产的勘查程度较高，而工业用白云岩、灰岩、耐火粘土、铝土矿等矿藏的勘查程度较底。

The reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.

对二级脱盐水系统中铁离子含量超标的原因，如来水水质发生波动、再生剂受到污染、预处理系统操作调整、床体运行切换等进行了论述。
