Scientific paper

The Elatina formation in South Australia, which provides a rich fossil record of presumptive solar activity in the late Precambrian, is of great potential significance for the physics of the Sun because it contains laminae grouped in cycles of about 12, an appearance suggestive of the solar cycle. This paper treats the laminae as varves laid down yearly and modulated in thickness in accordance with the late Precambrian sunspot activity for the year of deposition. The sunspot cycle period may have undergone secular changes. The evidence for an internal solar clock mechanism is strenghtened. A wave propagation zone intervening between the clock and the solar surface could produce the intrinsic spectrum.
