Imaggeo On Monday: The Ω shaped Voidokilia beach

Voidokilia beach is located on the Ionian coast of Messinia, in the southwestern part of the Peloponnese region, in Greece. While it is famous for its round shape reminiscent of the Greek letter Ω, it is considered one of the most beautiful beaches in the Mediterranean. It is separated by a strip of dunes from …[Read More]

GeoPolicy: Climate solutions at the center of focus this Earth Day

GeoPolicy: Climate solutions at the center of focus this Earth Day

Earlier this month, Climate Change 2022: Mitigation of Climate Change was published by the IPCC Working Group III as the third instalment of the IPCC’s Sixth Assessment Report (AR6). It emphasises that “rapid and deep” greenhouse gas emission reductions are needed across all sectors to have any chance of keeping the world below 1.5°C of …[Read More]

Imaggeo On Monday: A steady silent witness

Imaggeo On Monday: A steady silent witness

I took this picture during a sunny field work day in the Mara Wetland, Tanzania. The granitic inselberg appeared to me as a huge silent witness not only of siltation and inundation of the wetland but also of the human actions. Slash-and-burn is widely used to deforest lands and riparian vegetation for new crops and …[Read More]

Imaggeo On Monday: Stands of Time

Imaggeo On Monday: Stands of Time

Within the heart of the Malagasy Hauts-Plateaux, the rolling grasslands are pitted by deep incisions locally referred to as lavaka (‘hole’ in Malagasy). These mass failure features provide vast quantities of terrestrial matter to local freshwater arteries, accounting for over 80% of the annual sediment load of the Betsiboka River. The collapse of the overlying …[Read More]

Imaggeo On Monday: The Heart of a Stone

Imaggeo On Monday: The Heart of a Stone

Heart-shaped glomerocryst (aggregate of phenocrysts) made of plagioclase and pyroxene in a cordierite-bearing dacitic lava from Lipari (Eolie Islands). I study the crustal xenoliths of these lavas to understand the processes accompanying high-temperature metamorphism and crustal melting. But I came across this spectacular glomerocryst and couldn’t help but take a picture! Polarized light photomicrograph. Crossed …[Read More]
