The Lahontan Mountains quadrangle is located 11 km east of Fallon, Nevada at the southeastern margin of the Carson Sink (Fig. 1). Principal physiographic features include the Lahontan Mountains, collectively consisting of Sehoo, Eetza, Salt Wells, and Rainbow mountains. This quadrangle is part of the greater Lake Lahontan area that in part occupied the southern Carson Desert, previously mapped ...

Introduction Geology involves measurement, calculation and modeling. Everyone would agree that these are mathematical activities. Geology also involves classification. “In geology we tend to classify everything” (Thomas and Thomas, 2000, p. 571). This observation is certainly borne out by the GeoRef database. On 29 June, 2001, a search under the keyword “classification” brought up 60 papers wit...

3D modeling and visualization of geology volume is very important to interpret accurately and locate subsurface geology volume for mining exploration and deep prospecting. However, it faces a lack of information because the target area is usually unexplored and lacks geological data. This paper presents our experience in applying a 3D model of geology volume based on geophysics. This work has r...

Karstand cave-systems are complex, 3-dimensional phenomena. Mapping and visualizing them represents a challenge to cartographers, morphologists and computer-graphics-specialists. Surveying and sketching of cave-maps as well as the construction of 3D-cave-models (incl. geology) are important parts of cave exploration and research. Besides supporting the efforts of speleologists, cave maps and 3D...

Introduction The special issue of this journal (Nov. 2000) that was devoted to “Some Great Ideas for Geoscience Courses,” included nine ideas under the heading “Earth materials.” Six of those papers involved classification (Thomas and Thomas, 2000; Dowse, 2000; Reynolds and Semken, 2000; Harper, 2000; Christman, 2000; Niemitz, 2000). Classification of rocks and minerals is obviously a necessary...

Geoaesthetics is the project of making aesthetic sense of nature through geological phenomena. The aesthetic appreciation of nature has recently become urgent because of the serious influence of the natural environment on human beings. The author’s geoaesthetical research is categorized into three problems: art in geology or geology in the arts as the close relationship between art and geology,...

southern Omineca Belt, fieldwork was undertaken in 1987 to examine the geology of the Eagle River fault in the eastem Shuswap Highland. The Eagle River fault is a west-sidedown low-angle normal fault that juxtaposes low to mediumgrade metasedimentary and metavolcanic rocks of the Paleozoic Mount Ida Group atop high-grade gneisses of the Shuswap metamorphic complex (Figure 1-4-1 inset). Regional...

One of the most powerful pieces of knowledge that students can gain from the study of geology is an understanding of the immense scale of geologic time. In my introductory-level physical geology course at Northern Virginia Community College, we discuss geologic time about one-third of the way through the semester, after a thorough review of plate tectonics and the rock cycle. Because this subje...

The aim of this study is to assess the relationship between geological background and habitats of mushrooms. The study area is Grevena, a Prefecture of Greece well known for the great variety of the fungal flora and its distinctive geology. Thematic maps of the study area were produced with the use of GIS, taking under consideration geological formations, elevation, ecosystems and land use. Fin...
