The ore-hunting indicator is of calcite-potassium feldspar veins containing pyritohedron pyrite.
直接找矿标志为含五角十二面体黄铁矿铁方解钾脉。
Therefore, the albitization of plagioclase is shown in the early stage of diagenesis and albitization of potash feldspar appears only in the late stage of diagenesis.
因此,钠化可见于成岩早期,而钾钠化只发生于成岩晚期。
The middle oil-member is characterized by medium-sized sandstone and pebbled sandstone, with fair sorting and subangular sphaericity.Rock types mainly were feldspar debris sandstone.
油组主要沉积砂岩和含砾砂岩,粒度整体较粗,分选性较好,磨圆度以次棱角状为主,岩类型为岩屑砂岩。
The feldspar group contains tectosilicate minerals with similar properties, including orthoclase, albite and labradorite. Feldspars make up more than 60% of the upper crust of the earth.
系列包含网状矽酸盐矿物并且有相似属性,包括正,钠以及拉.构成了60%上层地壳.
