Geological Cycles

Some geological cycles notes from the past studies of cycles and geology.

Sedimentary Climate Cycles

In 1996 Malcolm McClure wrote:

The Geological Sociey London, has just published Special Publication 85 on the subject of sedimentary cycles co-edited by M.R. House. and A.S. Gale It is called Orbital Forcing Timescales and Cyclostratigraphy. In his intro House lists the factors as follows:

1. Earth-Sun distance (perihelion and precession cycles: 19 & 25 ka)

1. Tilt in Earth’s axis with respect to ecliptic (obliquity cycles 41 & 54 ka)

Additional summary

The remainder lists further orbital and sedimentary factors, including eccentricity, lunar nodes and seasonal interactions, and provides a CRI-oriented entry point into cyclostratigraphy.
