One woman's quest for geological understanding!

UncategorizedCategory Archives

It has been a while….

…. but then I have been working on my project course!  I handed in my work at the end of September and am not patiently waiting for my result!  Well, not so patiently, really….

Other than that, I am catching up on work and trying to get more in to facilitate a possible MPhil/PhD at Keele University   :)

Soooo need to be researching again!  I am going to be lost without the OU library! And I missed focussed geological research and associated structure!

Off Topic: Fundraising

On the 24th September 2014 I will be chopping off my >27cm of hair and donating the hair and money raised to the Little Princess Trust, in loving memory of Helen Andrews, who lost her fight with cancer last year.

I HATE having short hair…. I am no good with styling products, and the most adventurous hair style I do is to put my  >27cm long hair in pig tails rather than my signature ponytail.  But I am doing this in loving memory of my friend Helen Andrews, who died of cancer on 27/8/13.

“I will be watching over you all so please keep me entertained”.

Well Helen, for the next year – or maybe 2 – you can laugh at my struggle with hair styling!

“Tuning fork” graptolites

graptolites final

This is a slab of slate with many specimens of the “tuning fork” graptolites, Didymograptus murchisoni.

Graptolites are very imported index fossils in the zoneation of the British Ordovician.
These are from the Llanvin Series, Abereiddy Bay, Dyfed, South Wales.

Baryte in Thin Section

This is a thin section of  radial growths of Baryte (or Heavy Spar).

This slide shows plumose (literally like feathers) interference structure.

In thin-section it is similar to other sulphates but can be distinguished by its straight extinction, moderately high relief, small 2V and paragenesis.

  • Crystals are often intergrown, rosettes, as demonstrated in this TS.
  • Four cleavage directions.
  • Interference colors rangeup to first-order yellow.
  • Sometimes pale colors-brown in PPL with weak pleochroism.

Collected from a mineral vein in the Hope Valley, near Castleton, Derbyshire.

GEOLOGY OF WHITBY: Why do the East and West cliffs look different?

When you next take a stroll along the Pier at Whitby, stop at the light house, and look back towards the town. You will notice that the cliffs on either side of the pier look very different to each other. Why?

THE EAST CLIFFS

East Cliff

The East Cliffs have lots of horizontal layers of dark and light rock—shales and sandstones.

Fossil of the week: “Horn Coral”

Heliophyllum (or “Horn Coral”) is an extinct Genus of Coral that existed predominantly in the
Devonian (408-360 million years ago).
This well preserved specimen was found in the beechwood limestone (Clark County, Indiana, USA)

This picture of the Heliophyllum horn coral shows the beaded pattern along its septa lines.

SXG390 – the project course!

After a slow start, I’m on a roll…. papers everywhere, highlighters at hand, a small mountain of pens and pencils …. SXG390 success here I come!

Its a strange thing, making “big” decisions regarding the topic – on one hand I am well motivated and fairly certain regarding what I want to look at, and on the other, I feel that I have to complete the research before coming up with the title!  Been on the phone to my (Phd) brother regarding tips in reading, and made many contacts, but at the end of the day, I have to sit down and learn to make efficient notes and not waste time reading fruitless papers!

ho hum…. procrastination needs to come to an end and I had better get back to it!

Check out new website: 3D fossils – official launch 22/8/13

The GB3D Type Fossils Online project is in the process of developing a database of fossils found in the UK, including links to photographs and a selection of 3D digital models!

 

Quick fix post

My apologies for briefness – time is flying here….

After a wonderful week with the Oxford Geology Group in Tenerife, i’ve been dropped back down to Earth with a thump and am getting very absorbed in work…. and not the geological kind!

There will be some write ups very soon, but to whet your appetite in the mean time, here is a pic of Teide…

PS aced TMA02 for oceanography so things are looking up there too!
