Dave Green - Planetary Geology
Mon, 16 April, 19:30 – 21:30
Planetary Geology. Monday 16th April, for 10 weeks, until 9th July (not 7th nor 28th May). The state of knowledge of the planets of the solar system has improved vastly in the past 40 years as a result of space missions and improved technology for observation and analysis. The course will examine the results of this activity and evidence for these interpretations in terms of the internal structure, magnetism and geophysics of these bodies; their tectonics and volcanism, the effects of impacting bodies, and the surface conditions –atmospheres, oceans, sedimentary features and biology. Held at Wynstones School, Stroud Road, Whaddon, Gloucester from 7.30-9.30pm on Mondays. Cost £70.

SWGA Excursion - The Two Ridges, Cefn Onn, Cardiff, with Stephen Howe
Sat, 21 April, 10:00 – 16:00
Meet at 10.00am in the car park at Cefn Onn Country Park, Cardiff (ST 179 837 / CF14 0EP) (map)

Saturday 21st April: The Two Ridges, Cefn Onn, Cardiff: a geological ramble

Leader: Stephen Howe

Meet at 10.00am in the car park at Cefn Onn Country Park, Cardiff (ST 179 837 / CF14 0EP), which is located just north of the Lisvane/Thornhill railway station in north Cardiff. There are toilets in the car park but none afterwards until our return.

On this ramble we will walk up the southern rim of the South Wales Coalfield, along the two ridges and back down to Cefn Onn along paths that are a combination of tarmac, gravel, and earth. The ascent to the top of the ridges, which will be at a gentle pace, involves a vertical climb of 170 m (550 feet) and, on the return leg, the path is quite steep at first and, depending upon the time and weather, may involve negotiating a long flight of steps.

We will be looking at the structure and stratigraphy of the southern rim of the coalfield where the rocks range in age from the St. Maughan's Group of the Old Red Sandstone up to the top of the Carboniferous Limestone, which here is heavily dolomitised. We will also look at the remains of the industrial history of the area. There are extensive 360-degree views from the ridge top that allow the geology of the surrounding area and coalfield to be appreciated - weather permitting! The
total walking distance is approximately 5 kms
