The frequency with which certain simple motifs appear in these oldest sites has led rock-art researchers to adopt a descriptive term—the Panaramitee style—a label which takes its name from the extensive rock pavements at Panaramitee North in desert South Australia, which are covered with motifs pecked into the surface.

答案是：
because motifs primary assosiated with the Panaramitee region are common in the oldest sites the term Panaramitee style has become the general term for rock art of this type.

小菜我实在是不明白原句哪里有因果，并且貌似我没有划清句子的svo，麻烦牛牛出手相助啊，小菜我先抱拳啦~
O(∩_∩)O
我划的成分，望指点：

"The frequency with which certain simple motifs appear in these oldest sites" = "motifs primary assosiated with the Panaramitee region are common in the oldest sites"

"has led＋blabla" 就是这个这个原因（"motifs primary assosiated with the Panaramitee region are common in the oldest sites"）导致的结果.
