Massive Australian Precambrian/Cambrian Impact Structure Massive Australian Precambrian/Cambrian Impact Structure The Massive Australian Precambrian/Cambrian Impact Structure also known as MAPCIS is a proposed impact structure based upon arguments presented by Daniel P. Connelly at Geological Society of America meetings. Its center is located approximately equidistant between Uluru (Ayers Rock) and Mount Conner in Australia's Northern Territory. The structure is approximately in diameter. However, a hypothetical outermost ring in diameter is claimed to be the result of undefined far field stresses. Connelly argues that the age of this hypothetical impact is approximately 545 mya which puts it just before the Cambrian explosion (542 mya) of the
Attraction (grammar) "which flowers" that appear just before the verb due to WH-movement. Object attraction also appears in SOV constructions in Dutch, where agreement attraction occurs between the verb and the local object noun. Case attraction is the process by which a relative pronoun takes on (is "attracted to") the case of its antecedent rather than having the case appropriate to its function in the relative clause.
