Secondary porosity is the additional porosity created by subsequent chemical changes, especially fissures, fractures, solution vugs, and porosity created by dolomitization.

次生孔隙度则是由后生化学变化，特别是裂隙，断裂，溶洞和白云石化作用而产生的附加孔隙度。

The origin of dolomites is a research topic attracting great attention in sedimentology. Many dolomitization models have been invoked to interpret the origination of virious diagenetic dolomites. However, the genesis of earlyformed dolomites has long been an enigma in sedimentology, often referred to as the "Dolomite Problem".

白云岩的成因是沉积学界倍受关注的研究主题；众多的白云岩化模式可以用来解释各种成岩白云岩的成因；然而原生白云岩的成因一直是困扰沉积学界的难题，被称为"白云岩问题"。

Therefore, lowly ordered dolomite crystals show high reactivity in alka li solutions. Temperature tends to diminish the influence of ordered index on de dolomitization reaction of dolomite crystals.

Trontium isotope test analysis indicates that relationship exists between~(87)Sr/~(86)Sr ratios and the variation of seawater, evolution of palaeo-geographicalconditions in the region of Tazhong is the direct factor which controls the change ofthe 87Sr / 86Sr ratios and dolomitization is also an important factor.

r同位素测试分析表明，~(87)Sr/~(86)Sr比值与海水变化有关，塔中地区古地理环境演化是~(87)Sr/~(86)Sr比值变化的直接控制因素，白云石化作用对~(87)Sr/~(86)Sr比值有着重要作用。

The compaction fluid system of Hongyan basin formed Hongyan pyrite ore belt in the old upheaved region that situated at the edge of the basin, and at the same time the impressing dolomitization occurred.

红岩地区盆地压实流体系统在盆缘古隆起地段形成红岩型黄铁矿矿带的同时，还形成特征的白云岩化作用。

Thedevelopment of high quality reservoir has close relationship with dolomite types, atthe same time it appears different geochemical characteristics;In contrast,geochemical characteristics can verify the dolomitization type in turn, which offer theevidences for dolomite diagenic.

优质储层的发育和沉积相、白云岩化类型密切相关，表现出不同的地球化学特征。
