这个是什么石头？有价值吗？
这个石头是在煤矸石里面捡到的 ，颜色古铜色，重量上比一般石头重！请问是什么石头 有价值吗？ 滥竽充数者绕行！ 谢谢！！！
是火成岩碎块。
火成岩由岩浆（Magma）直接凝固而成。高温之岩浆在从
液态冷却中结品成多种矿物，矿物再紧密结合成火成岩。化学成分各异之岩浆，最後成为矿物成分各异之火成岩，种类繁多，细分之有数百种。如依其含矽量之高低做最简明之分类，火成岩有酸性（Acidic）、中性（Intermediate）、基性（Basic），及超基性（Ultrabasic）四大类。同时火成岩之晶体，因结晶时在地下之深度 不一亦有粗细之别；将此分别代表深浅之粗细做为矿物成分以外之另一分类依据。
火成岩可分成如次之种类：晶体粗大之酸性火成岩为花冈岩（Granite），细小至肉眼不能辨识者为流纹岩（Rhyolite）；晶体粗大之中性火成岩为闪长岩（Diorite）细小者为安山岩（Andesite）；晶体粗大之基性火成岩为辉长岩（Gabbro），细小者为玄武岩（Basalt）；晶体粗大之超基性火成岩为橄榄岩（Peridotite），此种火成岩无晶体细小者。晶体特大之火成岩统称伟晶岩（Pegmatite），但应指明其为伟晶花冈岩、伟晶闪长岩，或伟晶辉长岩。此外，不论其成分如何，岩浆在地面凝固时通常不暇结晶。此等不结晶火成岩均为火山岩，或成块状无结构之玻璃，酸性及中性者成黑耀石（Obsidian）或浮石（Pumice），基性者成玻璃质玄武岩（BasalticGlass），或在喷发时破碎成火山角砾岩（VolcanicBreccia）或凝灰岩（Tuff）。 火成岩以岩基或岩脉形体侵入较古岩层，倘再穿至地面，则成火山。 火成岩不仅为一切其他岩石之原料及多种矿产之母体，且为全球水分之来源。不论在深处或浅处，火成岩通常仅在地壳正有犟烈活动之时之地出现，并非一时处处或一处时时有为火成岩前身之岩浆活跃。岩浆在地下或喷出地表后冷凝形成的岩石。又称岩浆岩。大部分火成岩是结晶质的，小部分是玻璃质。火成岩的形成温度较高，一般介于700～1500℃之间。岩浆在地下冷凝固结形成的岩石称侵入岩；喷出地表冷凝固结形成的岩石称喷出岩。火成岩主要由硅酸盐矿物组成，在地壳中具有一定的产状、形态。许多金属矿产与非金属矿产都与火成岩有关，有时它本身就是重要的矿产资源。
具有收藏价值，用玻璃框罩上放在书柜里很雅致。

从颜色看不是煤精石啊。因为形成煤炭的植物中含有铁、铜、锌等物质，又因为有不少植物有吸聚各种矿物质的能力。所以当这些植物被埋入土中形成煤炭时，这些矿物质就有可能凝聚成矿核。煤矸石中有时就会发现金属元素很高的矿物，它们很重，并且甚至有金属光泽。
只是一块经过长途搬运、像鹅卵石一样被磨平棱角的黄铁矿，在未被磨平的部分还可以隐约看到其正立方晶体的轮廓。
