There are two types of diabaseprophyrite dikes in the third member of the Cretaceous Yingcheng Formation at the Shanghewan area in the southeastern uplift of the Songliao Basin.

During the Late Cretaceous the Taipingyan diabase porphyrite dikes with NNE strike emplaced into the eastern part of the Guidong composite granitoids in northern Guangdong Province.

Selecting the representative test area,the technology of high-pressure cement-chemical compound grouting is adopted to carry out experimental research on grouting reinforcement treatment of diabase dikes for determining grouting technique,and the effect and mechanism of reinforcement,etc.

Based on petrochemical and geochemical studies,the paper comes to the conclusion that the pyroxene porphyrite bodies are an alkalic basalt series,which have generated from the different evolutionary stages of a primary magma,i.
