they also can have giant stair-like terraces that have been formed because of the slumping of walls. The edges of the crater are usually elevated as compared to the surrounding areas. It is also termed a rim. If we talk about ejecta, it is the material of the rock that is basically...

Here, we introduce the discovery of the approximately 10 km diameter Santa Marta impact structure in Piau铆 State in northeastern Brazil. Santa Marta is a moderately sized complex crater structure, with a raised rim and an off-center, approximately 3.2 km wide central elevated area interpreted to...
As craters increase in size, a transition occurs to “complex” craters that are shallower in relation to their sizes, with flatter floors, and which develop a central peak as crater size continues Generation of geological maps, digital elevation models, and morphometric statistics Interpreting ...
expressed as dykes and lesser extent sills. Crater facies are pervasively observed in Orapa and Jwaneng kimberlite pipes in comparison with hypabyssal (or root zone) facies in Mengyin and Wafangdian pipe clusters. (4) Orapa A/K1 and Jwaneng mines are a few diamondiferous kimberlitic pipes ...
The gratifying sound of hitting a metal target is reason enough to invest in one. But the safety benefits of steel targets are even more important. Targets made from soft, deformed, or misshaped materials can crater and send dangerous ricochets back toward the shooting line. ...
Lignocellulosic biomass (LCB) is a low-cost and abundant source of fermentable sugars. Enzymatic hydrolysis is one of the main ways to obtain sugars from biomass, but most of the polysaccharide-degrading enzymes are poorly efficient on LCB and cellulases
The results show that water moved differently through different layers of rock, revealing a more complex history of groundwater activity in the Gale Crater than previously thought. We found that the Greenheugh Pediment (a broad, sloping surface that cuts across older layers of rock)...
The complex problem of the geological nature of the Seligdar deposit, an apatite occurrence of a type previously unknown in the crystalline shields, has been repeatedly discussed in the literature over several decades. Recently, hypotheses of its origin as exotic to the shield (a collapse ca1...
However, these geomorphological variables are not sufficient to represent a complex landform object's whole structure from a high-resolution DEM. Moreover, the amount of the DEM dataset is limited, including the landform object. Considering the challenges above, this paper reports an integrated model...
