The collapse of the overlying laterite exposes a comparatively nutr ...[Read More]

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 pho ...[Read More]
