Arran 2009 Field Trip – Day Four

Twitter Updates for the 8th of April. (RJ – Robert Jamieson (me), HS – Hazel Scott). Most of the day spent mapping Dougrie field, with a stopover at Imachar to look at Dalradian folding.

8:19 AM Apr 8th : Up bright(ish) and earlyish, weather was horrendous last night, not much better this morning. – RJ

10:35 AM Apr 8th : Mapping a field today without an os map. Using paces and bearings. Cold but dry – HS

The morning was spent practicing mapping techniques by mapping Dougrie Field, an area with Dalradian Rocks, Old Red Sandstone and a Dolerite Dyke.

12:03 PM Apr 8th : Mapping outcrops on a field using compass clinos, pacing and our wits. – RJ

The light came out quite strange for this photo, but you get the idea.

1:36 PM Apr 8th : Taking a break from mapping for lunch. – RJ

Lunchbreak

2:47 PM Apr 8th : Second mini bus to be stuck in mud. Full day of mapping complete. Field split by ig. Dyke and a fault. Vern won stare off with a rock? – HS

3:47 PM Apr 8th : Hard hats required in bus, very bumpy road! Saw some awesome folds and micro folds in imachar beach. – HS

3:50 PM Apr 8th : Some small folds in Dalradian rocks. – RJ

Some small scale folding

After Imachar we went back to North Glen Sannox and walked across a transect of the Highland Border Group; looking at pillow lavas, agglomerates and black slates along the river bed. Since we were in a bog and the weather was shocking I decided not to risk tweeting from my iPhone.

6:59 PM Apr 8th : Putting on after sun – somehow still got burnt despite heavy rain. (Ginger gene). – RJ

7:11 PM Apr 8th : Back in the flats and cooking dinner now. weather is lovely now, forecast for tomorrow is awful! Corrie tomorrow i think. – HS

As might be rather obvious by now, the weather occupied our minds for most of this trip. Days three and four were probably the worst.

9:15 PM Apr 8th : Completed geological map of Dougrie Field. – RJ

12:13 AM Apr 9th : Finished writing up notes from today. Lots of interesting structural bits and pieces today. – RJ

I hadn’t realised that I’d been working quite that late.
