Morphology and emplacement of flows from the Deccan Volcanic Province, India

In the citing paper

“A simple expression of flow morphology is lava-lobe thickness, as this represents the essential morphological difference reported from CFB p ahoehoe (phh) lavassheet-lobe-dominated (simple) vs. hummocky-lobe-dominated (compound) lavas (e.g., Walker, 1971;Bondre et al., 2004;Sheth, 2006;Jay et al., 2018).”

In the citing paper

“Lava flow morphology, especially flow thickness, is a fundamental characteristic of CFBs that is potentially linked to lava-flow eruptive rates (e.g., Bondre et al., 2004).”

In the citing paper

“Based on our two traverses that include significant Kalsubai (lowest) and Lonavala (middle) Sub-group lava sequences (Matheran and Varandah Ghats), there appears to be a slight prevalence for small-lobe-dominated (or hummocky phh) lavas in those formations, in accordance with previous studies (e.g., Bondre et al., 2004).”

In the citing paper

“Whole sub-groups of the Deccan have indicative thickness PDFs (Figures 5B, 6B) that support some of the conclusions of previous studies (Bondre et al., 2004), in that the lower, older subgroup (Kalsubai) formations together have the most peaked and thinnest mode, and the upper sub-group (Wai) has the broadest mode with a mean thickness similar to that for the middle subgroup (Lonavala) formations.”

In the citing paper

“While some studies (e.g., Bondre et al., 2004) have argued for a relationship between eruption rates and flow lobe thickness, some other modern analog studies (e.g., Thordarson and Self, 1998) and experimental work (Rader et al., 2017) have not found a systematic relationship.”
