Explore the Earth, Maps and Satellite Images

Google Maps and Google Earth are very common platforms today to explore maps and satellite images of the earth. But there are many other ways to explore the earth. Some are listed here.  1.   Earth Explorer This map is developed by USGS helpful to obtain earth imagery across available geo-spatial data types. Users can navigate via interactive map or text search to obtain Landsat satellite imagery, Radar data, UAS data, digital line graphs, digital elevation model data, aerial photos, Sentinel satellite data, some commercial satellite imagery including IKONOS and OrbView3, land cover data, digital map data from the National Map, and many other datasets. Users can search by exact location via the interactive map or input specific coordinates to view what data types are available. 2.   Sentinel Hub This platform developed by  Sinergise has Sentinel, Landsat, and other Earth observation imagery easily accessible for browsing, visualization and analysi...

Granites in Nepal Himalaya

Granites are distributed in three parallel belts in Nepal Himalaya 1.      Paleozoic Granites ·        They are  Cambro-Ordovician age. ·        They are found in thrust sheets of Lesser Himalaya, Kathmandu Nappe and Dadeldhura Nappe. ·        The granites are made up of biotite-rich and tourmaline-rich varieties . ·        They are closely associated with the adjacent gneisses, which display a similar mineral composition. ·        Several concordant, tabular granite bodies, up to 200 m thick, are intruded. ·        Some well-known bodies are Palung Granite, Agra Granite, Dadeldhura Granite   2.      Higher Himalaya Leucogranites ·        They are of Tertiary age and occur as several plutons, very many dikes, and veins. ·  ...

Photogeological Map of Central Nepal (Stocklin and Bhattarai, 1982).

  Photogeological Map of Central Nepal (1:100000) was published in 1982. It was mapped by J. Stocklin and K.D Bhattarai.  The map represents part of the Lesser Himalaya of Central Nepal to th ewest of the Kathmandu Valley and to the south of the Manaslu-Ganesh Himal sector of the High Range.

Geology Of Nepal

The Himalaya was formed due to collision of Indian Plate and Eurasian Plate at about 40 million years ago. It extends in 2400km east - west direction. Its width varies from 230 to 320 km and bounded between the Indo-Gangetic Plain in the south and Tibetan Plateau in the north. Nepal Himalaya occupies the central 800km part. Heim & Gansser 1939 , and Gansser 1964 divided the rocks of the Himalaya into four tectonostratigraphic zones that are characterised by distinctive stratigraphy and physiography. From south to north, it can be divided into five latitudinal morpho-tectonic zones and these are : 1. The Gangatic Plain (Terai) 2. The Sub Himalayan (Chure or Siwalik) 3 Lesser Himalayan (Mahabharat Mountain Range), 4. Greater Himalayan, and 5. Tibetan Himalayan zones (Tethys Himalaya). Each of these zones is clearly identified by their morphological, geological and tectonic features. Main Frontal Thrust (MFT), Main Boundary Thrust (MBT), Main Central Thrust (MCT) and South Tibetan ...
