1. Early in the nineteenth century,encounters with Aboriginal rock art tended to be infrequent and open to speculative interpretation, but since the late nineteenth century, awareness of the extent and variety of Australian rock art has been growing.

2. The frequency with which certain simple motifs appear in these oldest sites has led rock-art researchers to adopt a descriptive term—thePanaramitee 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.(句子简化题：隐含的因果逻辑关系。)
3. Certain features of these engraving slead to the conclusion that they are of great age—geological changes had clearly happened after the designs had been made and local Aboriginal informants, when first questioned about them, seemed to know nothing of the irorigins. Furthermore, the designs were covered with “desert varnish,” a glazethat develops on rock surfaces over thousands of years of exposure to the elements. (集中列举：排除题出处。)
4. In the 1970s when the study of Australian archaeology was in an exciting phase of development, with the great antiquity of rock art becoming clear, Lesley Maynard, the archaeologist who coined the phrase “Panaramitee style,” suggested that a sequence could be determined for Australian rock art, in which a geometric style gave way to a simple figurative style (outlines of figures and animals), followed by a range of complex figurative styles that, unlike the pan-Australian geometric tradition tended tomuch greater regional diversity.(信息量很大的长句，先划分成分再翻译。)
