SEM-BSE图像、显微照片和CL图像显示成岩组件。(a)细粒度砂岩具有凹凸的纹理联系人。方解石(Cal1)晶体表现出微弱的就像颗石藻crosspattern形态。大斑点的方解石(Cal3)包括置换和水泥阶段。微晶水泥发生在石英石英颗粒,Mcs1, 4060, Endrőd调频。(b)铁白云石水泥晶体白云石粮食。置换方解石(Cal3)包括小碎屑钾长石的残余,M7, 4103, Szolnok调频。(c)砂岩Szolnok形成的特点是线性颗粒接触。成岩矿物包括置换和水泥方解石(Cal3)、钠长石和高岭石,M7, 3410, Szolnok调频。(d)的CL图像视野(c)所示。碎屑钾长石的淡蓝色发光包括nonluminescent成岩钠长石。碎屑的钠长石绿色蓝色荧光的颜色(空箭头)高岭石中存在。 Postcompactional calcite (Cal3) exhibits dull red luminescent color (filled arrows), well M7, 3410 m, Szolnok Fm. (e) Vuggy porosity (blue resin) includes secondary intragranular pores, which are typical in calcite (stained pink) and K-feldspar (stained yellow) and secondary, dissolution-enlarged intergranular pores, which are characterized between framework grains. Kaolinite occurs next to K-feldspar, well K1, 3020 m, Algyő Fm. (f) Quartz with straight crystal face indicates authigenic overgrowth cement precipitation. Postcompactional calcite (Cal3) engulfs quartz cement, well K1, 3036 m, Algyő Fm.
