Forearc Depressions Develop in Warm Subduction Zones by Underplating‐Induced Crustal Flexure
Terra Nova, EarlyView.ABSTRACT We propose a model for forearc depression formation in warm subduction zones. Forearc depressions overlie some ocean‐continent subduction zones and form between a forearc high and volcanic arc. Forearc highs coincide with 51–91 mGal free‐air gravity anomalies and km‐scale reflector bands in seismic sections, indicating they comprise crust ...

Terra Nova, EarlyView.ABSTRACT The flexural profile of a foreland basin is controlled by lower plate strength and the magnitude of (sub)surface loads. Assuming that lower plate strength remains largely constant during flexure, changes in the flexural profile hint at reorganisations of (sub)surface loading.

Pegmatites of Southern California [PDF]
, 1954 For many years the southern California region has attracted the attention of geologists interested in pegmatites and pegmatite deposits, largely because of the well-known gem and lithium occurrences in San Diego and Riverside Counties. These world-famous

Terra Nova, EarlyView.ABSTRACT The Carboniferous‐Permian Tarija basin of southern Bolivia evolved under major tectonic and climatic influence. The timing of transition from glacially influenced to arid conditions, after the Gondwanide tectonic event, has been based mainly on palynological correlations.
