The isomorphism problem for graph magma algebras
(One-value) graph magma algebras are algebras having a basis B = V boolean OR {1} such that, for all u,v is an element of V, uv is an element of {u,0}. Such bases induce graphs and, conversely, certain types of graphs ...

The Carran-Los Venados volcanic field and its relationship with coeval and nearby polygenetic volcanism in an intra-arc setting
(Elsevier, 2015)
Understanding the relationship between monogenetic and polygenetic volcanism has been a long-standing goal in volcanology, especially in cases where these two styles of volcanism are coeval and geographically adjacent. We ...
Reconciling mechanical models of caldera ring-fault nucleation within the transcrustal magmatic system paradigm
(Elsevier B.V., 2024)
© 2024 Elsevier B.V.The formation of a collapse caldera requires the nucleation of circumferential ring-faults that connect an underlying magma chamber with the Earth's surface. The roof of the magma chamber collapses as ...
Sr/Ca-Ba/Ca systematics of volcanic rocks from the Central Andes, southern Peru, and its implication for Andean magmatism
(Geochemical Society of JapanJP, 1984)
Ca, Sr and Ba contents of 186 volcanic rocks (andesites, dacites, rhyolites, basalts, basanites and shoshonites) collected from the central Andes volcanic zone, southern Peru, have been determined by a inductively coupled ...
