Ngempon Temple is one of the historical sites around Mount Ungaran area. result Hindu civilization in Indonesia which was built VIII-IX century. This research conducted area because it necessary to conserve associated with geological study aims determine aspects that have potential become geotourism The methods used are mapping for field data collection and petrographic analysis rock characteri...

The El'gygytgyn impact structure in Chukutka, Arctic Russia, is the only impact crater currently known on Earth that was formed in mostly acid volcanic rocks (mainly of rhyolitic, with some andesitic and dacitic, compositions). In addition, because of its depth, it has provided an excellent sediment trap that records paleoclimatic information for the 3.6 Myr since its formation. For these two m...

PLAINS MATERIALS pvs VERY SMOOTH PLAINS MATERIAL—Occurs as smooth planar surfaces only in floors of c 4 and c 5 craters (FDS 529126). Very few superposed craters at Mariner 10 resolutions. Interpretation: Probably shock-melt and fallback associated with formation of individual craters ps SMOOTH PLAINS MATERIAL—Forms flat to gently rolling plains in extremely large annulus surrounding Caloris Ba...

    Introduction Epithermal deposits are usually found in association with near-surface magmatic-hydrothermal environments with volcanic rocks. According to studies, their formation depth is less than 1.5 km and the temperature for their formation is less than 300 ° C. Epithermal deposits are usually rich in gold to gold-silver and rich in silver and include low sulfide, medium sulfide and hig...

Detailed work on Quaternary volcanism has been carried out in the Mermoz and Fann sectors of western Senegal. In sector, main emission zone is a collapsed crater located at intersection three major fractures: NE-SW, NW-SE N-S. The lithological succession this sector comprises, from bottom to top: 1) substratum with its base Eocene limestones which lie sands surmounted by stratified tuffs; 2) ve...

the base (cu–pb–zn) and precious metals (ag±au) mineralization at the no. 4 anomaly of golojeh deposit occurred in volcanic and sub–volcanic eocene–oligocene host rocks, in the central part of the tarom–hashtjin zone. basic to intermediate volcanic, volcaniclastic and sub–volcanic rocks are dominated in the area and include andesite, basaltic andesite, trachy-andesite, dacite and tuff with affi...

neyshabour turquoise mine is located in northwest of neyshabour, southern quchan volcanic belt. eocene andesite and dacite forming as lava and pyroclastic rocks cover most of the area. subvolcanic diorite to syenite porphyry (granitoids of magnetite series) intruded the volcanic rocks. both volcanic and subvolcanic rocks are highly altered. four types of alteration are recognized including: sil...

Introduction: The Rochechouart impact structure is a deeply eroded, late Triassic impact site located in south-central France [1,2]. Rochechouart impactites comprise five main lithological units from the base of the structure upwards, originally described as follows: unit 1) shocked autochthonous basement rock; unit 2) finely crystalline melt rock; unit 3) red 'welded' breccia/suevite; unit 4) ...
