The Himalaya-Tibetan orogen has become the paradigm for continental collision and is central to deciphering continental tectonics. Neogene extension in the orogen is not predicted by plate tectonic theory, and its significance is widely debated. In the Himalaya, north-south extension is restricted to the Southern Tibetan Detachment System (STDS), which juxtaposes the High Himalayan Crystalline ...
The analysis of large datasets of music audio and other representations entails the need for techniques that support musicologists and other users in interpreting extracted data. We explore and develop visualisation techniques of chord sequence patterns mined from a corpus of over one million tracks. The visualisations use different representations of root movements and chord qualities with geo...
Risk management stakeholders in high-populated volcanic islands should be provided with the latest high-quality volcanic information. We present here the first volcanic susceptibility map of Lanzarote and Chinijo Islands and their submarine flanks based on updated chronostratigraphical and volcano structural data, as well as on the geomorphological analysis of the bathymetric data of the submar...
This article is a collaborative project by six members of an Internet community of lesbian mothers called MOMS. MOMS is a diverse community of lesbian mothers that is inclusive of bisexual and transgender women, as well those planning to become parents. The article outlines the history of the group and how the moderators have created an environment that encourages diversity. Members of the MOMS...
Alkali lamprophyre dykes of southern Amlash have been injected into the upper Cretaceous limestones and pillow lavas without any special trend. Based on this research the following results obtained: 1- On the basis of Mg, Fe, Ti, Al contents, three different types of mica has been identified. A: Mg enriched biotite as the first generation. B: Ti enriched biotite as the second one. C: Fe...
Field observations and unmanned aerial vehicle surveys from Caldera Taburiente (La Palma, Canary Islands, Spain) show that pre-existing dykes can capture re-direct younger ones to form multiple dyke composites. Chill margins suggest the older were solidified cooled when this occurred. In one example, an 40Ar/39Ar age difference of 200 kyr was determined between co-located dykes. Petrography geo...
