Abstract

Lamprophyre (camptonite) was found in the southern most part of the Nakanogawa group. This camptonite occurs as dyke in pelagic sediment surrounded by basic tuff matrix. The camptonite is composed of alkali feldspar, kaersutite, salite, biotite, opaque minerals, apatite and aegirine-augite. K-Ar dating of the camptonite indicates an age of 95 Ma. The camptonite was emplaced in the environment of oceanic islands or sea mount during Cenomanian. -from English summary
