Salt deposits and moisture threaten to destroy the Mohenjo-Daro excacation in Pakistan, the site of an ancient civilization "that flourished at the same time as the civilizations" in the Nile Delta and the river valleys of the Tigris and Euphrates.

这句话的正确形式就是这样的，可是这个句子的结构我不是很清楚，有谁能告诉我这个句子的主语和动词是什么吗？ 还有后半句里，as的前面部分的中心词是the site,而后面部分的中心词是the civilization,as的前面部分和后面部分不会不一致吗？

S: Salt deposits and moisture
V: threaten to destroy
O: the Mohenjo-Daro excacation

.the site of an ancient civilization .....是同位语，修饰O：the Mohenjo-Daro excacation

关于the site of an ancient civilization that flourished at the same time as the civilizations in the Nile Delta and the river valleys of the Tigris and Euphrates.

"that flourished at the same time as the civilizations in the Nile Delta and the river valleys of the Tigris and Euphrates" 是定语，修饰civilization.

所以应该是civiliation flourished at the same time as the civilizations in the....., civilization vs. civilizations
