Mud Volcano Biogeochemistry

, 2020
Mud volcanoes are frequently encountered geo-structures at active and passive continental margins. In contrast to magmatic volcanoes, mud volcanoes are marine or terrestrial, topographic elevation built from vertically rising fluidized mud or mud breccia.

A reevaluation of the late quaternary sedimentation in todos os Santos Bay (BA), Brazil

Anais da Academia Brasileira de Ciências, 2000
Todos os Santos Bay is a large ( 1000 km²), structurally controlled tidal bay in northeast Brazil. Three main drainage basins debouch into the bay, providing a mean freshwater discharge of 200 m³/s (prior to 1985), or less than 1% of the spring tidal ...
