A long-lived silicic magma chamber may form within so-called Deep Crustal Hot Zones when basaltic magmas are repeatedly emplaced into continental crust (Annnen et al., 2006) and …

2012年9月1日 · A magma chamber is a partially or totally molten body located in the crust and supplied with magma from a deeper source, a reservoir (Fig. 1). While active, a magma …

2015年1月1日 · Oddly enough, although the physical nature of this active magma chamber is known in detail, its chemical composition is not nearly as well known. This is quite the reverse …

2006年11月1日 · A magma-chamber ruptures and initiates a dyke when the following equation is satisfied (Gudmundsson, 1990): (1) p l + p e = σ 3 + T 0 Here, p l is the lithostatic stress or …

2009年7月15日 · The magma chamber starts to be sill-like and, if emplacement rates are high enough, it eventually evolves towards a bell shaped chamber (Fig. 3). Because new injected …

2019年5月1日 · Chamber is the deformable recipient space for the incoming magma. The areas of the roof and/or side walls (A 2) increase as more magma is continuously forced into the …

2020年11月1日 · A more traditional, ‘pro-magma-chamber’ approach considers layered intrusions as having crystallized from a large mass of the long-lived, slowly fractionating melt in magma …

2022年1月1日 · Effect of magma injection rate on the time series of surface uplift (a), magma temperature (b), chamber volume (c), crystal volume fraction (d), chamber mass (e), and …

2006年2月1日 · Since the magma chamber is known to be located inside the flat caldera of Sierra Negra at shallow depth (Amelung et al., 2000), we simplify the problem and assume an elastic …

2011年3月8日 · The early transitional tholeiitic basaltic magma formed a mafic magma chamber which, at some stage, may have reached 5 km in diameter and was frequently subject to new …
