Island arcs have narrow, segmented volcanic fronts which may reflect a similar segmentation in the downgoing plate. Secondary volcanic centers appearing some 3-4 m.y. later than the front and at some distance behind the front are common to most island arcs. Secondary arc volcanism in the Aleutian, Kamchatka, Kurile, Japan, Indonesia, and Scotia arcs is examined to expose correlations between lava chemistry and volcano position relative to the segmented front. Potash is universally higher, as… 

Upper Plate Stress Controls the Distribution of Mariana Arc Volcanoes

We present a spatial analysis of volcano distribution and morphology in the young, intraoceanic Mariana Arc. Both the quality of fit to idealized models and the divergence from those ideals indicate

Origin of Subduction Zone Magmas Based on Experimental Petrology

More than 70% of the subaerial volcanoes of the Earth are distributed at convergent plate boundaries such as in the Andes, Cascades, Aleutian Islands, Japan, and New Zealand. It is widely accepted

Geology of Amak Island, Aleutian Islands, Alaska

Amak Island is a young, small volcano near the western tip of the Alaska Peninsula, 50 km north of the otherwise sharp Aleutian volcanic front. Here a geologic map of the island, chemical analyses of

The dykes and structural setting of the volcanic front in the Lesser Antilles island arc

The orientations of dykes from many of the islands of the Lesser Antilles island arc have been mapped. Most of these dykes can be interpreted in terms of local or regional swarms derived from

A third volcanic chain in Kamchatka: thermal anomaly at transform/convergence plate boundary

The Kamchatka volcanic arc, which is located at the northern edge of the Kurile arc, consists of three volcanic chains, all parallel to the trench axis. In contrast, most subduction zones have only

Types of quaternary volcanic activity in Northeastern Japan

The northeastern Japan forms a typical arcuate structure with a remarkable zonal arrangement of many geologic features, including the distribution of Quaternary volcanoes. Thus two distinct zones of

Quaternary volcanic and tectonic segmentation of Central America

Central America is divided into seven segments based on differences in the strikes and positions of volcanic lineaments in the historically active volcanic chain. This block-like pattern is also seen

The Aleutian Arc: Tectonic blocks, episodic subduction, strain diffusion, and magma generation

A relocated earthquake sequence in the western Aleutian arc lasting from February 1965 through December 1968 is shown to map an episode of subduction of the Pacific plate. The February 4, 1965, Rat

Comparative volcanology and petrology of the atlantic island-arcs

Comparisons are made between the Lesser Antilles and the South Sandwich Islands, the recent volcanic island chains at the eastern margins of the Caribbean and Scotia arcs. Although situated in

Mechanism of magma ascent and deep feeding channels of island arc volcanoes

The paper discusses the mechanism of deep magma activity beneath island are volcanoes and similar structures on the basis of data from geophysical investigations in Kamchatka; the analyses of forces

Andesitic Volcanism and Seismicity around the Pacific

Close correlation between content of potash in erupted lavas and vertical depth to the Benioff zone suggests that andesitic volcanism has its origins in the mantle where magmas are generated by events associated with earthquakes of intermediate focal depth.
