abstract: Abstract. The genesis of Mount Tempel which is part of Mount Mujil is still being debated by
some geologists discussing the Kulon Progo Mountains. The surface and subsurface
measurements must be done to know a geological aspect that building the area around Mt. Mujil,
precisely in Tempel Hill on the northeast side of Mt. Mujil, Girimulyo, Kulonprogo, Yogyakarta.
The geology of this location is still a mystery and has always been a hot topic regarding origins,
geotourism, and disasters. The general problem in this study is related to the occurrence of the
northeast side of Mt. Mujil which is still not final and much debated, so it is necessary to
approach the concept of volcanic geology to help answer these problems. The purpose of this
study was to identify the physical characteristics of igneous rocks in Tempel Hill based on
surface and subsurface data. The approach method is carried out through geological mapping,
geophysical resistivity measurements, and petrological, petrographic and geochemical analysis.
The results of the petrological analysis show that the igneous rock has a porphyroafanite –
microcrystalline texture without a flow texture, some scoria – massive structures, geochemically
it shows that calc – alkali refers to subduction products. On the other hand, resistivity analysis
shows the presence of volcanic rocks with density values and resistivity values of intrusive rocks
and volcanic breccia in the vicinity. Indications of the presence of volcanic rocks with an area
the size of Tempel Hill are defined as magma fossils or subvolcanic intrusion rock bodies.
Tempel Hill has potentially for tourist attractions that can improve the welfare of local residents.
