From south to north, the zones and the major faults separating them are the Main Frontal Thrust (MFT), Subhimalaya Zone (also called Sivalik), Main Boundary Thrust (MBT), Lesser Himalaya (further subdivided into the "Lesser Himalayan Sedimentary Zone (LHSZ) and the Lesser Himalayan Crystalline Nappes (LHCN)), Main Central thrust (MCT), Higher ...
Nepomorpha is an infraorder of insects in the "true bug" order . They belong to the "typical" bugs of the suborder Heteroptera. Due to their aquatic habits, these animals are known as true water bugs. They occur all over the world outside the polar regions, with about 2,000 species altogether.
In geology, metasedimentary rock is a type of metamorphic rock. Such a rock was first formed through the deposition and solidification of sediment. Then, the rock was buried underneath subsequent rock and was subjected to high pressures and temperatures, causing the rock to recrystallize. The overall composition of a metasedimentary rock can be ...
Waterbug or water bug can refer to any of several things: True bugs. The true water bugs (Nepomorpha), including such insects as giant water bugs, creeping water bugs and backswimmers; Various other aquatic true bugs, known collectively as water bugs; Heteroptera; Cockroaches. The American cockroach, Periplaneta americana; The German cockroach ...
Hagen called them Khumbu Nappes, and Lumbasumba Nappes. [19] Arita calls it the Himalayan Gneiss Group, [16] and it lies above the MCT II, or the upper MCT. The High Himalayan Crystalline units (HHC) [20] are mainly composed of kyanite- to sillimanite-grade gneisses intruded by High Himalayan leucogranites at structurally higher levels. [21]
Pleidae, the pygmy backswimmers, is a family of aquatic insects in the order Hemiptera (infraorder Nepomorpha, or "true water bugs").There are 37 species in three genera, distributed across most of the world, except the polar regions and remote oceanic islands.
These "typical" bugs (suborder Heteroptera) are commonly called semiaquatic bugs or shore-inhabiting bugs. The Ochteroidea (infraorder Nepomorpha are also found in shore habitat, while the Gerromorpha are actually most often encountered running around on the water surface, being kept from sinking by surface tension and their water-repellent legs.
Metavolcanic rock is volcanic rock that shows signs of having experienced metamorphism. [1] In other words, the rock was originally produced by a volcano, either as lava or tephra. The rock was then subjected to high pressure, high temperature or both, for example by burial under younger rocks, causing the original volcanic rock to recrystallize.
