Dyke to sill deflection in the shallow heterogeneous crust during glacier retreat: part I
Dykes and sills occupy Mode I (extension), Mode II (shear), or hybrid mode fractures and most of the time transport and store magma from deep...

Dyke to sill deflection in the shallow heterogeneous crust during glacier retreat: part II
Changes from dyke to sill propagation in the shallow crust are often caused by dissimilar layer properties. However, most previous studies have not...

Cooling processes of a dolerite sill inferred from the variations in plagioclase aspect ratio, Atsumi District, north-eastern Japan
The upper Kayaoka sheet in the Atsumi area, Northeast Japan, has an alkaline-basaltic composition. The modal olivine and Ni enrichment in the lower...

An andesitic sill complex in the Southern Permian Basin: volcanogenetic model and stratigraphic implications
Subvolcanic intrusions are highly variable in shape and structure, and occur in nearly all parts of the upper crust, as a result of extensive...

A broadband magnetotelluric survey for Mt. Meakandake volcano with special attention to the unrest during 2016–2017
We performed a broadband magnetotelluric (BBMT) survey and three-dimensional resistivity modeling for the Meakandake volcano in eastern Hokkaido,...

A Field Based Perspective of the Volcanism in Tadpatri Formation of Proterozoic Cuddapah Basin, India: An Analog of the Deccan Traps?
Field studies around Pulivendla (14°33′36″N: 78°19′48″E) belonging to the Tadpatri Formation of Proterozoic Cuddapah Basin document three distinct...

A Rare Occurrence of Deformed Tholeiitic Basalt Sill (Amphibolite) from Mesoarchaean Ghattihosahalli belt, Western Dharwar Craton, Karnataka
This paper records the occurrence and significance of a rare sill of tholeiitic basalt composition emplaced into the Mesoarchaean Ghattihosahalli...

Subvolcanic Intrusions
Volcanic plumbing systems are made by complex networks of dykes, sills, laccoliths, cryptodomes, and other intrusions, which may interconnect to...

Lake-level fluctuations and paleovegetation during the Houghton phase of glacial Lake Minong
The Houghton phase was a brief period of low water in the glacial Lake Minong (ancestral Lake Superior) basin during the early-mid Holocene. Previous...

Developments in the study of volcanic and igneous plumbing systems: outstanding problems and new opportunities
Prior to and during eruptions, magma is stored and transported within volcanic and igneous plumbing systems (VIPS) that comprise a network of magma...

Structural Setting and Heterogeneous Deformation of the Mesoproterozoic Granite–Gneisses of North Tianshan with the Example of the Karadjilga Massif (Kyrgyzstan)
AbstractA detailed structural study showed that the Mesoproterozoic Karadjilga granite–gneiss massif of the Kyrgyz North Tianshan represents a sheet...

Bathymetry constrains ocean heat supply to Greenland’s largest glacier tongue
Mass loss from the Greenland ice sheet has increased over the past two decades, currently accounting for 25% of global sea-level rise. This is due to...

Environmental Changes and Geomorphological Factors Influencing the Sediment Flux to a Coastal Lake Spanning the Deglacial- Early Holocene Period in East Antarctica
The geomorphological settings of the lakes in the coastal oases of East Antarctica play a significant role in the lake’s response to the local and...

The investigation of energy dissipation in ogee profile spillway model
Major failures of spillway occur due to the inadequate or inefficient design of the spillway. In the Khadakwasla dam spillway, Pune (Maharashtra) has...

Warming beneath an East Antarctic ice shelf due to increased subpolar westerlies and reduced sea ice
Understanding how climate change influences ocean-driven melting of the Antarctic ice shelves is one of the greatest challenges for projecting future...

Diverse late-stage (≤ 62.5 Ma) Deccan volcanism and plutonism in the Thane–Vasai region, Panvel flexure zone, western Indian rifted margin
The western Indian volcanic rifted margin, and its large-scale tectonic feature called the Panvel flexure, formed at 62.5 Ma during the late stages...

Komatiite Lavas and Intrusions
In this Chapter, we consider ultra-low-viscosity lavas. These are represented principally by Archean ultramafic komatiites which form integral...
