Lithotectonic Map of the Appalachian Orogen: Production Phase

主要由NSF-EAR赞助的阿巴拉契亚造山带的新岩石构造图的编制已接近完成。新地图结合了20多年来的新数据和新想法，这些数据和想法主要是对1978年发表的原始造山带构造岩相图的回应。从区域概念和应用的角度来看，原始地图对构造界产生了持久的影响。新地图即使没有更大的前景，也有类似的前景；新地图不仅使过时的原始地图焕然一新，而且还将纳入地理信息系统（GIS）的现代技术进步。因此，新地图为阿巴拉契亚山脉增加了一个全新的维度，并将超越原地图的功能，允许1 .构建新的主题地图；增加新的数据库；易于更新的岩石构造基础。地图制作成本的很大一部分由美国地质调查局和加拿大地质调查局共同承担；但是，它们无法支持地图制作的全部财政负担。在此，我们请求资金主要用于印刷新地图的硬拷贝。

Compilation of a new lithotectonic map of the Appalachian Orogen, sponsored largely through NSF-EAR, is nearly complete. The new map incorporates more than 20 years of new data and ideas that were generated mainly in response to the publication of the original Tectonic Lithofacies map of the orogen in 1978. The original map has had a lasting impact on the tectonics community, both from the standpoints of regional conceptualization and application. The new map has similar, if not greater, promise; not only will the new map give a significant facelift to the dated original, it will also incorporate modern technological advances in geographic information systems (GIS). Thus, the new map adds an entirely new dimension to the Appalachians and will surpass the capabilities of the original map by allowing for i. construction of new theme maps, ii. Addition of new databases, and iii. ease in updating the lithotectonic base. A substantial portion of the production costs of the map is being shouldered by a collaborative effort between the US Geological Survey and the Geological Survey of Canada; however, they cannot support the entire financial burden of map production. Herein, we request funds mainly for printing of the hard copies of the new map.
