Testing this hypothesis will contribute to our understanding of the evolution of the rift-lake cichlids specifically, and of the proximate mechanisms that have directed adaptive radiations in fish feeding in general.
Qualitative and quantitative integration and interpretation of magnetic, gravity and magnetotelluric data help to determine the internal architecture of the Jaibaras rift, and allow assessing the evolution of the Jaibaras Rift within the Precambrian crystalline basement of Borborema Province, NE Brazil.
Volcanism was predominantly controlled by the volcano-tectonic evolution of the Ohře Rift and culminated in the Lower Oligocene.
We divided the evolution of the Potiguar Rift into five stages based on these ratios and correlated them with the major tectonic stages of the breakup between South America and Africa in the Early Cretaceous.
The first is the study of the recent and present day tectonic evolution of the Rukwa rift (SW Tanzania) and the other, the study of the topography from the Bulusan volcano (Philippines).
Deciphering the long-term landscape evolution of these rift-related mountains is still in its infancy.
In this contribution, analogue modeling is used to provide new insights into the Nubia-Somalia kinematics responsible for development and evolution of the Main Ethiopian Rift (MER), at the northern termination of the East African Rift system.
Genik (1992) presented a model for the regional framework and tectonic evolution of the Cretaceous-Paleogene rift basins of Niger, Chad and the Central African Republic.
The structural dataset, integrated with available geochronological constraints, gives rise to a two-step (Miocene-to-Holocene) tectonic scenario in which the spatial migration of the volcanic activity towards the eastern boundary of the Transantarctic Mountains occurred during the evolution of the West Antarctic Rift System.
Four calibration points were invoked: we conservatively estimated the emergence of two main lineages at an upper limit of 3 Mya, and restricted the evolution of Gregory Rift montane isolates to the onset of the last glacial cycle, approximately 110 Kya.
Geomorphic evolution of these landscapes in relation to tectonic evolution of the Afro-Arabian rifts is the prime target of this study.
