STREAM GRADIENT INVESTIGATION IN THE BÜKKALJA USING INTERPOLATED SURFACES [PDF]
Acta Geographica Debrecina. Landscape & Environment Series, 2010 The geological, tectonic settings of an area can be examined with the analysis of drainage network. In the Bükkalja, the Miocene pyroclasts – mainly the welded ignimbrites – had taken decisive part in theevolution of drainage network.

Engineering Properties of Volcanic Tuff from the Western Part of Yemen
Sultan Qaboos University Journal for Science, 2018 This paper deals with a study of the physical and mechanical characteristics of volcanic tuff and ignimbrite from six quarries located at different areas in the western part of Yemen (Manakha, Jahran, Bakhran, Dar Al-Hanash, Abaser and Soraifa).

Earth Surface Processes and Landforms, Volume 51, Issue 10, October 2026.This study investigates three methodologies for measuring boulder axes in coastal boulder ridge deposits. Traditional Tape Measurements were statistically compared against handheld LiDAR data and digitised boulder perimeters from a UAV generated orthomosaic collected at the Grind o' da Navir, Shetland.

Nuées ardentes and Ignimbrites [PDF]
Nature, 1946 A MODERN text-book of volcanology by Prof. C. A. Cotton, published under the somewhat misleading title “Volcanoes as Landscape Forms”1, has recently been reviewed in Nature by Prof. Arthur Holmes2. The book is beautifully illustrated and well documented ; it thus fills a gap in British volcanological literature and is likely to be widely read by ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.Abstract Distributed basaltic volcanic fields commonly host minor but significant silicic magmas, the origin of which remains debated. At Harrat Khaybar (western Saudi Arabia; ca. 1.7 Ma to present), volcanic activity erupted compositions range from alkali olivine basalt to trachyte and comendite.

Tectonics, Volume 45, Issue 10, October 2026.Abstract Detrital zircon U–Pb geochronology from Triassic–Jurassic basins in the New England Orogen (NEO) constrains sediment provenance and episodic continental arc evolution along the eastern Gondwanan margin. Dominant zircon clusters at 270–230 Ma and 340–300 Ma in these basins were likely sourced from contemporaneous magmatism in the NEO ...

VolcanicaExplosive eruptions can disperse ash over hundreds of kilometers, but correlating proximal ignimbrites with distal ash-fall deposits remains challenging when units have similar ages and field characteristics. We studied twelve ignimbrites in the southern
