Abstract Remote sensing often used in geothermal exploration because it was considered has many advantages. The aim of this research is to extract and analyze the lineament density Libungo area based on a Digital Elevation Model (DEM). Lineament obtained from (DEM) satellite image data downloaded Geospatial Information Agency (BIG) page. processing uses Geomatica aplication automatically. Extra...

The 2020 Elliot Creek landslide-tsunami-flood cascade originated from an 18.3 Mm 3 rock slope failure in quartz diorite bedrock a valley undergoing rapid glacial retreat. We used airborne LiDAR and optical imagery to characterize the its surroundings. Using LiDAR, we determined that two rockslides (2020 older undated one) occurred on this shared common basal rupture surface. mapped main sets of...

[1] Hydrophones moored in the North Atlantic Ocean recorded a sequence of explosive, volcano-acoustic signals originated at the Walvis Ridge in the South Atlantic Ocean. 365 explosive signals were detected from the Walvis Ridge beginning 24 November 2001 continuing through March 2002. The largest swarm began on 19 December at 2329 GMT, and lasted 1.25 hrs producing 32 locatable events. Swarm lo...

Synopsis Newly-acquired regional geochemical data for the Down-Armagh (Northern Ireland) sector of the Southern Uplands – Down-Longford terrane are assessed by comparison with the equivalent dataset for southern Scotland. Despite the much thicker glacigenic cover to the Down-Armagh bedrock, the principal geochemical lineaments identified in the Southern Uplands are still apparent. Patterns of e...

7 The Tertiary continental strata of the Himalayan foreland basin are subdivided in two 8 groups, but the meaning of this subdivision was previously unclear. From the analysis of drill9 holes, seismic lines, dated sections, field outcrops and balanced cross-sections, we find that the 10 southward migration rate of the deposition pinch-out of the younger group is 19 ± 5 mm/yr and 11 equals the H...

Development and interpretation of morphometric maps are important tools in studies related to neotectonics and geomorphology; Geographic Information Systems (GIS) allows speed and precision to this process, but applied methodology will vary according to available tools and degree of knowledge of each researcher about involved software. A methodology to integrate GIS and statistics in morphometr...

The Itapuranga alkali granite and Uruana quartz syenite are large K-rich EW-elongated intrusions, in the central part of the Neoproterozoic Brasília Belt, central Brazil. They are associated with Pireneus lineaments, which cut the regional NNW-SSE structures of the southern part of the belt. SHRIMP and conventional U-Pb data for the Itapuranga and Uruana intrusions indicate crystallization ages...
