The mesoproterozoic mafic dyke swarms are extensively distributed in the central north china craton, which are not deformed and metamorphic, emplacing the pre - existed fractures, so the dyke swarms become the conspicuous marks to reconstruct the mesoproterozoic tectonic stress field of the central ncc. the mafic dykes in the northern block are transtensional while the dykes in the central and southern blocks are extensional. the mesoproterozoic tectonic stress field could be simulated on the analysis of the distribution and mechanical origin of the mesoproterozoic mafic dyke swarms in the central ncc. the simulation result shows that the mafic dyke swarms were formed in the extensional tectonic setting in the ncc in the mesoproterozoic time, which are related to the extension of the mesoproterozoic yanliao - zhongtiao aulacogens cross the central ncc
克拉通北部地塊的鎂鐵質巖墻群為張剪性，而中部和南部地塊為張性。根據華北克拉通中部中元古代鎂鐵質巖墻群的分佈和成因機制分析，來恢復模擬中元古代的構造應力場。數值模擬結果表明鎂鐵質巖墻群在中元古代形成於伸展的大地構造背景，與橫穿華北克拉通中部的燕遼-中條拗拉槽系的伸展作用有一定的聯系。 -
