It lies 16 miles (26 km) northwest of Sint Eustatius, with which it forms the northwestern termination of the inner volcanic arc of the Lesser Antilles. Its capital is The Bottom. Saba is actually the peak of an extinct volcano, Mount Scenery (2,910 feet [887 metres]), surrounded by ...
5.4. Arc or rift setting There are different viewpoints on the geodynamic setting of the Xiong'er volcanic rocks (e.g., Chen and Fu, 1992, Zhao et al., 2002b, Zhao et al., 2009). Some researchers have reported that the volcanic rocks formed in a continental arc setting, representing ...

Map showing the types of acoustic basement and spatio-temporal variation of volcanic activities in the southern East Sea. For the age of volcanic edifices (indicated by red, yellow, and blue colors), see Figure 12.4B. LO=Late Oligocene, LMM=Late Middle Miocene, MM=Middle Miocene, NUB=...
We assume a functional form y=mx+b in our regression, and consequently nonlinear rates will be obscured on this velocity map product. However, we note that maps of the L2 residual are useful for identifying regions that deviate from linear deformation. 5 Validation [17] In order to quantify...

An examination of sediment geochemical data from the HVA fore-arc areas in relation to their tectonic setting, the seismic activity and geophysical data led to the production of a map showing the areas of potential presence of metal sulfides on the rock basement. Maleas basin is one of these...
