在研究红层砂岩铜矿成矿规律和矿床成因的过程中,常会遇到构成岩石紫色和浅色的物质成分、岩石颜色的成因,以及其所代表的地质意义.通过几年的工作,我们把形成红层的紫色物质称为红铁尘.它分布广泛而普遍,在沉积成岩、成矿过程中具有很重要的意义;研究其地质过程有助于砂岩铜矿成因问题的解决和成矿规律的认识. 长期以来,人们都对红层的紫色给予一定的注意.在沉积矿物学、沉积岩石学和砂岩铜矿的研究中,认为形成红层的红色取决于其中所含的赤铁矿、褐铁矿和氢氧化铁等成分.例如,苏联普列奥勃拉任斯基等著的《沉积岩矿物》一书中指出:“形成于海底,含于盐矿层的红色夹层中;海成红色淤泥和粘土的红色取决于赤铁矿”.“杂
In studying the metallogenic regularity of red sandstone copper deposit and the genesis of the deposit, it often encounters the origin of the purple and light-colored materials, the color of the rock and the geological meaning of the rock.After several years of work, The purple material forming the red layer is called red iron dust.Its distribution is widespread and common, which is of great significance in sedimentary diagenesis and metallogenesis. It is very important to study the geological process to solve the genesis of sandstone copper deposit and mineralization Law .For a long time, people pay attention to the purple color of red layer.In the study of sedimentary mineralogy, sedimentary petrology and sandstone copper deposit, it is considered that the red color of red layer depends on the hematite , Limonite and ferric hydroxide etc. For example, in the book Sedimentary Rock Mineralogy by Pleven Oblast, the Soviet Union, it is stated that “in the red interlayer formed on the seafloor and contained in the salt deposit, Red muddy and clay red depending on the hematite ”."
