Abstract

Physical volcanology and emplacement mechanism of the Central Atlantic Magmatic Province (CAMP) lava flows from the Central High Atlas, Morocco

Highlights

The Central Atlantic Magmatic Province (CAMP) is one of the largest continental flood basalt (CFB) provinces on Earth [Marzoli et al, 1999] (Figure 1a, b)
Subaerial lava flows from the Moroccan CAMP can be grouped into two main categories: compound pahoehoe flows and simple flows
The former type is exclusively confined to the Lower and Intermediate fms while only simple flows occur in the Upper and Recurrent fms

Summary

Introduction

The Central Atlantic Magmatic Province (CAMP) is one of the largest continental flood basalt (CFB) provinces on Earth [Marzoli et al, 1999] (Figure 1a, b). This Large Igneous Province (LIP) extends for more than 7500 km from north to south. It may have covered over 10 million km, with a total volume of magma exceeding 3 million km3 [Marzoli et al, 2018]. The CAMP was emplaced during the early stages of breakup of the Pangean supercontinent that led to the opening of the Central Atlantic Ocean. The peak activity of the CAMP straddled the Triassic–Jurassic boundary, at ca. 201 Ma [Blackburn et al, 2013, Davies et al, 2017, Marzoli et al, 1999], and probably lasted less than 1 million years, while the late activity reached the Sinemurian [Marzoli et al, 2018]
