n.化成白云石

The dolomitization is dominated by mixed water dolomitization in the early diagenetic stage, followed by burial dolomitization. 白云石化作用，以早成巖階段混合水白云石化作用為主，埋藏白云石化作用次之。

The intraplatform point beach experienced good dolomitization and has good reservoir properties, with little development and thin thickness. 臺(tái)地內(nèi)點(diǎn)灘白云石化較好，儲(chǔ)集性能也較好，但分布狹窄，厚度較薄，無規(guī)律可尋。
