马拉维和坦桑尼亚伸展和岩浆作用研究（分段）项目获得了东非裂谷系马拉维北部（Nyasa）裂谷的一套全面的地球物理和地球化学数据集。在2012年至2016年期间，采集了陆上/海上主动和被动地震数据、长周期和宽带大地电磁数据、连续全球定位系统数据以及地球化学样本。这些数据的组合旨在阐明裂谷的沉积、地壳和上地幔结构、活动变形模式以及裂谷相关岩浆活动的起源和年龄。我们项目的一个独特组成部分是获取马拉维湖的地震数据，包括地震反射，陆上/海上广角地震反射/折射，以及湖底地震仪，拖曳拖缆和大型拖曳气枪源的宽带地震数据。
The Study of Extension and maGmatism in Malawi aNd Tanzania (SEGMeNT) project acquired a comprehensive suite of geophysical and geochemical datasets across the northern Malawi (Nyasa) rift in the East Africa rift system. Onshore/offshore active and passive seismic data, long‐period and wideband magnetotelluric data, continuous Global Positioning System data, and geochemical samples were acquired between 2012 and 2016. This combination of data is intended to elucidate the sedimentary, crustal, and upper‐mantle architecture of the rift, patterns of active deformation, and the origin and age of rift‐related magmatism. A unique component of our program was the acquisition of seismic data in Lake Malawi, including seismic reflection, onshore/offshore wide‐angle seismic reflection/refraction, and broadband seismic data from lake‐bottom seismometers, a towed streamer, and a large towed air‐gun source.
