铁方解石

In the course of groundwater towards the center of the depression cone, not only the dissolution of calcite, dolomite and hematite, the precipitation of siderite and melanterite may occur, but also the cation exchange between Na(superscript +) and Ca(superscript 2+), Fe oxidation-reduction of Fe may occur.

地下水在向降落漏斗中心区的径流过程中，不但发生了方解石、白云石和赤铁矿的溶解作用以及菱铁矿和水绿矾的沉淀作用，而且发生了Na与Ca(上标 2+)的交换、铁氧化－还原反应等一系列复杂的水－岩作用。

Carbonate cements are the most abundant authigenic minerals in the Palaeogene sandstones of Lishui sag, East China Sea basin .

碳酸盐胶结物是东海盆地丽水凹陷古近系储层砂岩中最为重要的自生矿物，主要类型为铁白云石和方解石。

Study shows that compaction and cementation can play a destructive role in Suining formation reservoir,while dissolution and fracturing can play a constructive role in that.The main facies of Suining formation are ferruginous-shale film,anhydrite,dolomite and calcite.The micro-fracture and grain-edged fracture mainly resulted from compaction fracturing,compaction slipping and tectonic dynamic force greatly improve the reservoir permeability.

研究表明：①对遂宁组储层起破坏作用的是压实作用、胶结作用和交代作用，而溶蚀作用、压裂作用则对储层起到建设性作用；②遂宁组最主要的成岩相组合为铁泥膜－硬石膏－白云石－方解石成岩相；③由压实破裂、压实滑动和构造动力形成的微裂缝、粒缘缝有效改善了储层的渗透性。

Plunder melds and run with this jewel!

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
