Multimodal artificial intelligence approaches using large language models for expert‐level landslide image analysis

Computer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract Climate change exacerbates natural disasters, demanding rapid damage and risk assessment. However, expert‐reliant analyses delay responses despite drone‐aided data collection. This study develops and compares multimodal AI approaches using advanced large language models (LLMs) for expert‐level landslide image analysis.

Comparison of the Thermometery-Barometery methods by using Thermocalc and Theriak-domino to study Calc- silicate Hornfelses in Cheshin, Hamedan

Journal of Economic Geology, 2019
Introduction The pseudo-section method, first proposed by Hensen (1971), is used today by scientists to determine the thermodynamic conditions of mineral crystallization and modeling in metamorphic lithology (Hoschek, 2004; Omrani et al., 2013).

Contact Metamorphism in Southern California [PDF]

, 1954
A highly condensed introduction to "Contact metamorphism in southern California" is obviously not the place in which to indulge in semantic niceties nor to engage in terminological tussles, and thus the title is not intended to reflect a carefully ...

Australian continental‐scale heavy mineral patterns track climate, weathering and erosion

Sedimentology, EarlyView.
ABSTRACT The heavy mineral cargo of sediment is influenced by a complex and variable overprint of climate and environmental processes acting on weathered crystalline basement sources. Here, a continental‐scale heavy mineral compositional dataset of 1315 surface sediment samples, analysed via automated mineralogy, from across Australia is utilized to ...

Early Cambrian U-Pb zircon age and Hf-isotope data from the Guasayán pluton, Sierras Pampeanas, Argentina: implications for the northwestern boundary of the Pampean arc [PDF]

, 2016
An Early Cambrian pluton, known as the Guasayán pluton, has been identified in the central area of Sierra de Guasayán, northwestern Argentina. A U?Pb zircon Concordia age of 533 ± 4 Ma was obtained by LA-MC-ICP-MS and represents the first report of ...

The Chamrousse Ophiolite (Western Alps, France): Relict of a Devono‐Carboniferous Ocean

Terra Nova, EarlyView.
ABSTRACT The Chamrousse ophiolite (Western Alps, France) is one of the best‐preserved Variscan relicts of Cambro‐Ordovician oceanisation within the northern Gondwana margin. This study presents new in situ U–Pb isotope analyses on zircon grains from that ophiolite, revealing that the oceanic stage in Chamrousse has occurred 150 Ma later than estimated.

Progress in the Application of Oxygen Isotopes in the Study of Petrogenesis

Yankuang ceshi, 2013
Since different types of rocks on the earth have different oxygen isotope compositions, they can be used to discuss the origins of various rocks and it has become a powerful tool for studying petrology.
