在查阅、综合前人资料的基础上,通过野外观察、采样,结合偏光显微镜和热分析的实验数据,分析了几种常见鲁砚石的矿物成分及形成的地质环境.研究结果表明:沉积岩类的鲁砚石矿物成分几乎以泥晶方解石为主,另含少量陆源矿物.变质岩类鲁砚石矿物成分以绢云母、绿泥石为主要矿物,另含石英,电气石等矿物.鲁砚石主要产于鲁西地块,形成期以寒武纪居多,形成环境多滨、浅海相,河湖相.

@@@@On the basis of previous data, through field observation and sampling, in combination of experimental data of polarizing microscope and hermoanalysis , mineral composition of some common Lu inkstones and the geolog-ical environment of these inkstones have been analyzed .It is found that sedimentary rocks are mostly composed of micrite calcite, with a small amount of terrigenous mineral; metamorphic rock type Lu inkstone are mostly com-posed of sericite and chlorite, with a small amount of quartz, tourmaline, etc.Lu inkstones are mainly found in western Shandong and mostly formed in Cambrian period with a preference of littoral , neritic, and lacustrine facies.
