文摘The macro- and microscopic results were that this body of basalt tectonically heavily loaded, strongly altered by clay minerals and characterized by hydro-metasomatic alteration. The geochemical analyzes revealed that the original magma could be a mantle origin of high iron and magnesium containing basalt （tholeiites, 10%-15%）. As regards to the palaeogeographic environment, it can be said that due to the periodic sea flooding, it pushed into a lower area, covered with sediment where the surrounding areas were highlighted （biikkszentkereszt and bukkszentlaszl6 tufts）.
