The eastern Anti-Atlas of Morocco represents one of the most completely exposed and perfectly documented biostratigraphic records of the entire Devonian worldwide. Paleogeographically it is clearly differentiated into shallow basins, pelagic platforms, and land areas which are newly defined and illustrated, one from the top of the Middle Devonian, the other from the middle Famennian as two of the most characteristic intervals. The dominant paleogeographic feature is the T-shaped Tafilalt Platform which, in spite of common unconformities and hiatuses, provides the best-documented biostratigraphic record through the entire Devonian. The westernmost termination of this platform was emerged during most of the Devonian (and locally even earlier) and became only flooded again by the Tournaisian transgression. In contrast to previous interpretations, this area is considered as autochthonous. In the Mader Basin subsidence was up to one hundred times higher with respect to the adjacent platforms, but water depth during the Middle Devonian to middle Famennian interval generally remained above storm-wave base. Devonian rocks are only patchily and incompletely preserved on the Mader Platform, which can be considered as an intermittently flooded peninsula connected to the Lower Paleozoic farther west. The major paleotectonic element of the entire area is the Great Anti-Atlas Fault, a sinistral strike-slip fault, which sharply confines the above-mentioned realms in the south.

摩洛哥东部反图集代表了全世界整个泥盆纪的最完全暴露和记录最完整的生物地层记录之一。从古地理上看，它明显地被划分为新定义和图示的浅盆地，中上层平台和陆地区域，一个来自中泥盆纪的顶部，另一个来自中部法美尼亚，是两个最具特征性的层段。T型塔菲拉特平台是主要的古地理特征，尽管存在常见的不整合面和裂隙，但在整个泥盆纪时期仍提供了记录最完整的生物地层记录。该平台最西端的终结点出现在泥盆纪的大部分时期（甚至在更早的地方），并且仅在图尔尼斯海峡的侵袭中再次泛滥。与以前的解释相反，该区域被认为是土生土长的。在马德盆地，沉陷相对于相邻台地而言高出一百倍，但中泥盆纪至法门尼中层间期的水深一般仍高于风暴波基数。泥盆纪岩石仅被零星地和不完全地保存在Mader平台上，该平台可被认为是连接至更西端的下古生界的断断续续的半岛。整个地区的主要古构造要素是大反阿特拉斯断层，这是一条左走向走滑断层，将南部的上述境界明显地局限在此。但是中泥盆纪至中部法美尼亚期的水深一般保持在风暴波基以上。泥盆纪岩石仅被零星地和不完全地保存在Mader平台上，该平台可被认为是连接至更西端的下古生界的断断续续的半岛。整个地区的主要古构造要素是大反阿特拉斯断层，这是一条左走向走滑断层，将南部的上述境界明显地局限在此。但是中泥盆纪至中部法美尼亚期的水深一般保持在风暴波基以上。泥盆纪岩石仅被零星地和不完全地保存在Mader平台上，该平台可被认为是连接至更西端的下古生界的断断续续的半岛。整个地区的主要古构造要素是大反阿特拉斯断层，这是一条左走向走滑断层，将南部的上述境界明显地局限在此。
