摘要描述了位于肯尼亚南尼扬萨霍马湾附近的乌萨基的一大批伊萨橄榄岩，以及来自霍马山的可比岩石和来自霍马-鲁里地区不同地区的捕虏体。文中给出了大多数岩石的模态分析，以及一些主要岩石类型和一些矿物的化学分析。讨论了这些岩石的成因，并提出它们的现代构成主要是通过交代交代作用而发展起来的。
Summary A mass of ijolitic rocks at Usaki, near Homa Bay in South Nyanza, Kenya, is described, together with comparable rocks from Homa Mountain and xenoliths from various parts of the Homa-Ruri area. Modal analyses are given of most of the rocks examined, together with chemical analyses of some of the main rock types and of some of their minerals. The origin of the rocks is discussed, and the suggestion made that their present constitution has developed largely by metasomatic replacement.
