| 5. | Both the metallogenic pressure and temperature are relatively lower , and the genetic classification of the ore deposit is epithermal deposit 成矿的温度和压力都比较低,矿床的成因类型为浅成低温热液矿床。 |
| 6. | In recent years , study of boron neutron capture therapy has been aimed at the establishment of epithermal neutron beams in order to avoid the open - skull surgury and for the treatment of deep - seated tumors 摘要近年来,硼中子捕捉治疗之研究倾向于采用超热中子束以避免切开头盖骨之手术及进行较深层之肿瘤治疗。 |
| 7. | In this article , the current status of epithermal neutron beams in the world is reviewed and also the design and construction plan of the epithermal neutron beam at the tsing hua open - pool reactor is reported 本文将介绍世界各国在设计建造超热中子照射管之现况,以及目前在国内清华水池式反应器建造超热中子照射管之进展及计划。 |
| 8. | The study of the regional geological setting , occurence mode of ore body , ore rocks , and orecontrolling factors of shiyintan gold deposit indicates that it is an epithermal volcanic hydrothermal gold deposit 摘要通过对石英滩金矿床区域地质背景、矿体产出形态、矿石特征、成矿控制因素的研究,认为矿床成因类型应属浅成低温火山热液型金矿床。 |
| 9. | The ore - forming material is mostly from volcanic rock , and sub volcanic rock provides the main thermal and some mineral materials . the ore - forming fluid is from meteoric water . as a result , it should be a kind of adularia - sericite type of epithermal gold deposit 成矿物质主要来自矿区火山岩围岩,次火山岩提供了主要热源和部分矿源,成矿流体来自大气降水,矿床成因类型为低硫化物冰长石?绢云母型浅成低温热液型金矿。 |
| 10. | The metallic mineral has very few content ( 1 % - 2 % ) , the mineral of ore is mainly of pyrite , chalcopyrite , limonite , aurum and electrum etc . the gangue mineral is composed of chalcedony , micro grained quartz , calsite , sericite , adularia , aragonite , chlorite , laumontite , pyrophyuite , kaolinite and so on , which show the typical mineral assemblage of epithermal 矿石为典型少硫化物型,金属矿物含量极少( 1 - 2 ) ,主要有黄铁矿、黄铜矿、褐铁矿和自然金、银金矿等。主要脉石矿物有玉髓、微粒石英以及方解石、绢云母、冰长石、文石、绿泥石、浊沸石、叶腊石、高岭石等,属典型低温矿物组合。 |
