Aeromagnetic patterns in Southern Uruguay: Precambrian-Mesozoic dyke swarms and Mesozoic rifting structural and tectonic evolution

Developmental Patterns in Mesozoic Evolution of Mammal Ears

Complex structures with significant biological function can arise multiple times in evolution by common gene patterning and developmental pathways. The mammalian middle ear, with its significant hearing function, is such a complex structure and a key evolutionary innovation. Newly discovered fossils have now shown that the detachment of the ear from the jaw, an important transformation of the m...

Discussion on structural evolution of Mesozoic Peninsular Malaysia

W. Altermann writes: In their discussion of palaeotectonics and palaeogeography of Malay Peninsula, Harbury et al. propose an alternative interpretation to Sengor’s (1984) model of Triassic or early Jurassic collision of the Cimmerian (Sibumasu) block with the Indochina block in the east. Their interpretation depicts Malay Peninsula as part of Triassic and lower Jurassic Australian Gondwana. ...

Mesozoic and Cenozoic tectonic evolution of the Shiquanhe area of western Tibet

[1] In the Shiquanhe area of far-western Tibet, midCretaceous strata lie unconformable on ophiolitic melange and Jurassic flysch associated with the Bangong-Nujiang suture zone. On the basis of our mapping and geochronologic studies, we suggest that these Cretaceous strata were shortened by >57% over a north south distance of 50 km during Late Cretaceousearly Tertiary time. The Late Cretaceous ...

Mesozoic Basin Development and Tectonic Evolution of the Dabieshan Orogenic Belt, Central China

Tectonic evolution of the early Mesozoic blueschist-bearing Qiangtang metamorphic belt, central Tibet

[1] A >500-km-long east-west trending metamorphic belt in the Qiangtang terrane of central Tibet consists of tectonic melange that occurs in the footwalls of Late Triassic–Early Jurassic domal low-angle normal faults. The melange is comprised of a strongly deformed matrix of metasedimentary and mafic schists that encloses lesser-deformed blocks of metabasites, Carboniferous–Triassic metasedimen...
