One woman's quest for geological understanding!

Procrastinated Incorporated

Well, I am neither packed nor motivated – as the dark skies are closing in, but providing no apparent relief, I sit on my sofa, watching the blue screen that WAS sky TV, and hoping it will actually start storming soon,so that we can all get some sort of relief from this uncomfortable heat and stickiness….They are waiting for a storm elsewhere, but it looks like it is going to bypass my house!

 

So, instead of packing, I am going to tell you about the exciting weekend which follows the week of real life!  I am off to North Cotswolds, Gloucestershire, for a course in graphic logging, which will be run by Dr Nick Chidlaw, who has so many letters after his name that I am sure that he must be counting in his head when reciting, or maybe he has a little musical ditty as an aide memoire!  (Don’t get me wrong – this is pure amazement, no sarcasm or anything else intended… I hope I have this many letters behind my name one day! I am currently BA BAEB EPTCE, and I need no song to remember that!)

So, this weekend I will be learning how to “succinctly communicate a wealth of sedimentary and stratigraphic information”. Friday and Saturday will be spent studying the stratigraphy visible at Hornsleasow Quarry, and then Sunday will be spent in the field making a “best” copy of the log I have managed to construct in the field…. to be honest I will probably end up drawing a stick by mistake, but that is exactly why I am going on this course:

This time on Monday, I will be the source of jealousy amongst my peers, as I show off my new skills at the SXR369 residential school in Durham:

  • systematically measuring thickness’s of rock units

  • correlating parts of the exposure being examined

  • determining lithologies, sedimentary structures fossil fauna/ flora and rock grain size

with confidence (yeah right, like THAT will really happen!)

Either way, any practice in this area will not go amiss – especially since our field books are handed in each day in Durham for marking :s

Will report more when I have read the background thoroughly (or at least roughly!), and am up to date with my reading for S369…..

Estwing Geological Belt Pack

What to pack for a geology field trip

Here I am, planning a busy week ahead (A market research trade fair in London, followed by a 3 day course in graphic logging in Gloucestershire) and I suddenly realised that it might be useful to add a checklist of what to pack for a geology field trip to my website.

I have done so, and this is now online here

CMA41 (SXR369) has now been submitted (for better or for worse…)

And I am really looking forward to the Graphic Logging weekend which is coming up soon…. Lots of “day job” stuff to do though first….

 Still working on the write up of the past two geology field trips – These WILL follow soon!

TMA02 Back – 76%

Well, im arguing one point, but otherwise I guess im content, but not overjoyed…. ho hum…. onto TMA03 for S369 and CMA41 for SXR369

I’m going to be listed on the a microchip on the Mars Science Laboratory rover heading to Mars in 2011!

Last chance to Send Your Name to Mars!

Kyanite

This is one of my favourite pieces – especially because it also contains  garnet, black tourmaline and mica!  It was a gift from my mother a few years ago, so no idea where it was collected…

  • Chemical Formula: Al2SiO5
  • Crystal symmetry: Triclinic
  • Crystal habit: Columnar; fibrous; bladed
  • Crystal system:Triclinic pinacoidal
  • Twinning: Lamellar on {100}
  • Cleavage: [100] perfect [010] imperfect with 79° angle between
  • Fracture: Splintery
  • Tenacity: Brittle
  • Mohs scale hardness: 4.5-5 parallel to one axis, 6.5-7 perpendicular to that axis
  • Luster: Vitreous to pearly
  • Streak: White
  • Pleochroism: Trichroic, colorless to pale blue to blue

Kyanite is one of  which are useful indicators of the conditions of metamorphism in metamorphic rocks.   (A polymorph is a mineral that shares the same chemistry but a different crystal structure with another, or other, minerals.)

The Al2SiO5 polymorphs are useful index minerals because they are very common in aluminous metamorphic rocks.  The presence of one of the polymorphs gives a broad indication of the pressure-temperature regime that the metamorphic rock attained.

Kyanite is formed at high-pressures and low-temperatures.

(The coexistence of two polymorphs in a rock provides more specific pressure-temperature information because they are restricted to a line in pressure-temperature space.  The coexistence of all three polymorphs defines a specific pressure and temperature of metamorphism.)

 

Finally some time!

Well, things are settling down here:

  • Projects are done, dusted and paid for
  • Geology assignments are complete (even if handed in late, and the next ones already looming…)
  • New projects are on the horizon
  • A new venture is in sight
  • Old books have been placed on ebay….

well, that is enough for now, isnt it?

So, I was thinking about the progress (or lack of progress) that I am making with this Blog.  It has been some time since I wrote something, because “real life” took over, and it is a shame… So, i have a plan!

Rather than stressing about all the blogs on trips that I am not managing to write, I will add one blog a week on a rock/fossil in my collection, and include pictures.

Now, I am not (as yet) a qualified Geologist.  I am a student and lover of Geology.

So, if there are mistakes/comments which are obviously incorrect, I would really value your  input!

I wish I could say that I found all rocks and fossils in my collection myself, but I did not.  So, you are not just relying on my lack of expertise, but also, potentially, those of others!

In otherwords: FEEDBACK WELCOMED!!

Recent Geology trips WILL be reported upon, but pending Trips (Castleton this weekend, Graphic loggin in Gloucester in July, and a weeks residential school) may interfer…. until then, I will make a start on the “Rock/Mineral/Fossil of the week”….

Enjoy!

Desperate times…

… a lot going on right now, so will update further in the coming week.

Nothing to report other than I owe you all loads on info on what I have been up to, but do not seem to have the time to do so!

Apologies, and the promise of more soon,

Daisy

Daisys not dumb….

….81% in TMA01 for S369 – dead chuffed!  :)
