Abstract
three place in Jawa that pre-teftiary and paleogene rocks are exposed, the other two are at Karangsambung, Central Java and Ciletuh, West Ja-va. Ihese rocks consist of metamorphics, igneous and sedimentary rocks where some of them able to proposed as geotourism sifes. The spesific rocks outcrope and o/so lfs spe-cific relation exposed at Bendungan, Sekarbolo, Watuprahu, Bukit Temas and Bukit Jo-kotuwo. The oldest rocks at the Jiwo Hills is pre-Teftiary Phillyte Lithodem, its consrsf phyllites, mica schist, chlorite schr.sf .and marble that unconformably covered by Eocene Gamping-Wungkal Formation. Phyllite Litodem and Gamping-Wungkal Formation are cutted by some Late Eocene to Early Oligocene (39.8, 33.2 dan 31,3 Ma) basaltic orogenic dyke. Ihese thee litologic units (formation) are unconformably covered by Oyo Formation that concist of calcarenite and marl stratification. The Geotoun-sm sites in the Jiwo Hills are the ideal places for the object study and researh for students and geologists. At last, we propose to preserue all the object geotourism at the Jiwo Hil/s as natural laboralory for earth sciences.
