密苏里州河流断裂带的地砾岩显示出系统的沉降环结构，含有来自远上方和远下方的包裹体，并由富含气体的碱性超镁铁质岩浆喷发产生。类似的岩浆在世界上许多地方都产生了双晶岩，并且已知与金伯利岩密切相关，可能是金伯利岩的母岩。
Diatremes in the Missouri River Breaks demonstrate systematic subsidence-ring structure, contain inclusions derived from far above and far below, and have been produced by gas-rich eruptions of alkalic ultramafic magmas. Similar magmas have produced diatremes in many localities in the world and are known to be closely associated with and probably parental to kimberlites.
