A coalfield in the Amakusa Islands, Kumamoto Prefecture. The coal-bearing Paleogene is widely developed, especially on the Kamishima and Shimoshima islands. The coal is anthracite, but much of the coal in the north has been carbonized by the intrusion of igneous rocks, and in parts of the north and the central and southern parts, much of the coal has been carbonized due to faults. The reserves are said to be about 70 million tons, but there are currently no operating coal mines. [Ohashi Shusaku] Source: Heibonsha World Encyclopedia, 2nd Edition Information |
熊本県天草諸島にある炭田。とくに上島,下島には含炭古第三系が広く発達している。炭質は無煙炭であるが,北部の石炭の多くは火成岩の貫入によって炭化が進み,北部の一部および中部以南では断層のために粉炭化している所が多い。埋蔵量約7000万tといわれているが,現在稼行炭鉱はない。【大橋 脩作】
