矿床的开采地质条件是什么?

碰撞钱板块还没有破碎、没有岩浆活动、没有造山带的形成等等,就没有成矿作用.

构造控矿
矿床或矿体会沿构造线方向出露,大部分的矿床与构造有关
例如油气与褶皱、断层泥中可能有金等贵金属

花岗岩属于火成岩,按变质岩来说,接触带是应该有变质岩矿物出现的；页岩是沉积岩,而板岩与大理岩都属于变质岩,板岩就是含砂、土质较多的页岩变质而来,板岩有点和片岩差不多,大理岩差不多就是灰岩和白云岩及二者的过渡岩变质而成的.

成矿特点包括成矿时间、空间、构造环境、温度压力等物理化学条件、矿石结构构造上的特点等,对于火山成因矿床等内生矿床,还要考虑介质、与围岩的接触关系等.
火山成因矿床的特点有：
1、矿床位于火山岩浆构造活动带内,矿区附近有同期的火山岩、次火山岩；
2、含矿介质复杂,有岩浆、喷气、热液及火山致热的海水湖水等；
3、矿床产生于地表或地下浅处,成矿温度可从1000°C至几十度；
4、矿体受火山机构控制明显；
5、矿石矿物成分及结构构造复杂多样.

晚期岩浆矿床是指在地质构造比较活动的条件下,由于受构造应力的作用,含矿残余岩浆被挤入岩体构造裂隙或附近围岩的构造裂隙中,形成贯入式矿体.
后生矿床是指在围岩形成后,在另一种地质作用下,含矿热液沿断裂、裂隙充填结晶而成矿床.
从他们的定义看晚期岩浆矿床也可以称之为后生矿床.后生矿床范围较晚期岩浆矿床大.

拿鲍文序列来比较.就是随着岩浆温度由高到低慢慢冷凝,铁镁硅酸盐结晶序列是橄榄石→辉石→角闪石→黑云母→石英→沸石,而钙钠硅酸盐结晶序列是：钙长石→培长石→拉长石→中长石→奥长石→钠长石.
岩浆矿床矿物以鲍文反应序列温度、压力高的矿物为主,橄榄石→辉石→角闪石为主.
风化矿床矿物石英、黄铜矿、白钨矿、锡石等等抗风化矿物、重矿物为主.

解题思路：根据图中元素周期表可以获得的信息：左上角的数字表示原子序数；字母表示该元素的元素符号；中间的汉字表示元素名称；汉字下面的数字表示相对原子质量，进行分析判断即可．

A．金属于金属元素，故错误；
B．根据元素周期表中的一格中获取的信息，可知元素的相对原子质量为197.0，相对原子质量单位是“1”，不是“克”，故错误；
C．相对原子质量=质子数+中子数，故中子数=197-79=118，故错误；
D．金的化学性质非常稳定，故正确．
故选D．

11矿床学的主要研究内容有哪些?
矿床学是研究在地壳中形成条件、成因和分布规律的科学.
矿床学以矿床为研究对象,其基本任务是：
第一,正确认识各类矿床的地质特征、形成条件和形成过程,查明矿串成因.
第二,查明矿床在时间上和空间上的烟花特征,认识矿床在地壳中的分布规律,以便预测在各种地质环境中,可以期望找到何种矿产和矿床类型.

MVT是密西西比河谷型(矿床)的简称.
一般将以碳酸盐岩作为容矿岩石并且赋存在公认的古喀斯特构造中的铅锌矿床称为“密西西比河谷型”矿床(MVT).之所以叫这个名字,是因为最早人们认为它们是美国密西西比河谷地区特有的一个矿床类型.美国的密西西比河谷上游,东南密苏里、三州交界区的矿区现在被看作是经典的MVT矿床产出区.
斑岩型矿床、喷气沉积型矿床（SEDEX）我不知道嗬对不起了
,矿床基本特征
矿体
个旧原生锡多金属矿主要矿床类型分为:层间硫化物锡多金属矿床和花岗岩接触带矽卡岩型锡多金属矿及脉状矿.主要矿点有:打磨山,马拉格,松树脚,芦塘坝,老厂,双竹,金光坡等
层间硫化物锡多金属矿
矿体形态呈层状,似层状,透镜状,条带状分布于个旧组层位中.部分矿体已为氧化矿,则称为层间氧化矿.此类矿体不但与岩浆作用有关,而且隐含着许多非岩浆热液信息.
矽卡岩型硫化物矿床
该类矿床主要产于花岗岩与白云岩接触带上,锡石及金属硫化物形成浸染状,网脉状和致密块状矿石,而矿体形态则多呈陡倾斜的脉状,柱状,缓倾斜的透镜状,似层状或不规则囊状,此外还在花岗岩超覆下盘产生"凹兜"状矿体.矿体形状受花岗岩与围岩接触面形态控制,与花岗岩作用极为密切.
热液脉状矿
矿区脉状矿床有石英脉黑钨矿床,电气石细脉带矿床,此类矿床其矿脉的产出直接受构造裂隙控制.
（刚刚学过,你真幸运啊!这答案想了老半天的）

搞清以下问题：
1、所谓原生晕,就是矿体周围不同元素的含量等值线图的联合,其中应分出原生晕的前缘晕、近矿晕和尾晕三大类.
2、岩浆矿床的特征：矿体与岩体之间的关系密切,矿体就产于岩体内部或边部.
3、岩浆矿床的形成过程中,原生晕与之同时形成.
因此,他们之间经常具有一定的重合性.至于原生晕的不同套合形态,主要取决于成矿条件及成矿特征,也就是说与相应的岩相有关.

解题思路：（1）工业上为提高稀硫酸浸取效率一般采取的措施有：提高反应温度、增大反应物的接触面积等；
（2）将石棉的化学式改写为氧化物的形式方法为：活泼金属氧化物、较活泼金属氧化物、二氧化硅、水；
（3）过程②中加氨水调节溶液的pH等于6，完全沉淀时其pH＜6的氢氧化物都能完全沉淀．

（1）工业上为提高稀硫酸浸取效率一般采取的措施有：提高反应温度、增大反应物的接触面积等，所以可以采用粉碎红帘石而增大接触面积、提高反应温度的方法，
故答案为：①粉碎红帘石；②提高反应的温度；
（2）将石棉的化学式改写为氧化物的形式方法为：活泼金属氧化物、较活泼金属氧化物、二氧化硅、水，所以石棉的氧化物化学式为：3MgO•3SiO₂•2H₂O，故答案为：3MgO•3SiO₂•2H₂O；
（3）过程②中加氨水调节溶液的pH等于6，完全沉淀时其pH＜6的氢氧化物都能完全沉淀，根据表中数据知，Fe（OH）₃、Al（OH）₃，完全沉淀时需要的pH都小于6，所以滤渣的成分是Fe（OH）₃、Al（OH）₃
，故答案为：Fe（OH）₃、Al（OH）₃．

点评：
本题考点： 电解原理；物质分离和提纯的方法和基本操作综合应用．

考点点评： 本题考查了物质分离和提纯方法的综合应用，要从整体上分析各个步骤发生的反应、反应原理等知识点，这种题涉及的知识点较多，但都较基础，根据教材中基础知识采用知识迁移的方法分析解答，题目难度中等．

岩浆矿床形成与岩浆岩岩性、岩相的关系,成岩成矿在时间上、空间上,物质成分上的一致性.随着岩浆的分化,温度逐渐降低,岩浆中含有的气体便分离出来,这时气体具有很大的压力,因此活动性很强,容易侵入到岩石的裂缝中 去,冷却凝结形成矿床.在冷凝过程中,矿物结晶一般粗大,因此形成 的矿床就叫做伟晶岩矿床.它是长石和云母的来源.
当岩浆侵入岩层时,自然要和它周围的岩石发生接触,因而就影响周围的岩石矿物发生变化,从而可能在接触带形成矿床.这种由接触作 用而形成的矿床,就叫做接触矿床.这一类矿床主要有铁、铜、铅、锌 等.

楼主,要区分具体的什么矿藏,不同的矿藏的形成的地质条件是不相同的,比如水晶,它的形成必须在地下2公里深处封闭的、有足够的空间、温度下降缓慢的条件下,还有其他的热液矿床,也必须有封闭的和有利的空间地质条件,才能使岩浆中的挥发份有富集、富存的地质边界条件.

Yanzi Dong deposit is located in northern Yunnan Lanping County,mountain ash mining area,is part of Lanping basin.(Through the deposit,geological,geochemical characteristics of the study,could be the following conclusions:
1,mineralization to the Mesozoic marine continental transition to the construction of the carbonate rocks,volcanic rocks construction folder-based construction,Himalayan tectonic Nappe and hydrothermal into a leading role.
2,according to the sulphur ore,lead isotope analysis results reflect a deep source of minerals with characteristic sulphur ore with the characteristics of the deep sulfur,lead for the crust and mantle mixed lead.Deposit mineralization occurred in the open system,a source of minerals for the deep mantle material,mixed shell source material.
3,because the deposit into the crust deep in the epithermal copper-silver deposit,for the period of mineralization Himalayan; mineralization:in the long-term,multi-phase construction of deep crustal movement and the role of hydrothermal circulation,or rock formation Mineralization in the activation of elements that were transferred to solution,and the rich hydrothermal mineralization integrated,long-term activities of the deep fault structure will be shallow hydrothermal-oriented,structural favorable position in the targeted mineralization.
