Dactyliocerous inverted

My avatar picture.
This was taken using a scanner in the days before I had a decent digital camera. I just put the fossil directly on the scanner glass. Works quite well, I think. Subsequently edited and inverted.

Pear leaves 'pleochroic halos'

nobody@ipernity.com (Earthwatcher) — Tue, 11 Oct 2016 00:10:43 +0000

Earthwatcher has posted:

The fungal rust spots on the pear tree leaves remind me of the pleochroic halos often seen in biotite mica crystals in thin sections of rocks prepared for petrological microscopy.

Beach pebbles, Budleigh Salterton

Earthwatcher has posted:

The beach pebbles at Budleigh Salterton are beautifully coloured, and especially lovely when wet, near the edge of the sea. They are mostly derived from the local eponymous Pebble Beds of Triassic age, although there are some older pebbles from the Devonian and older rocks further west.

A closer view of the hinge zone of the fold in the previous photo. The 'space problem' of accommodating the beds in the hinge zone of the fold is well illustrated here. The thickened hinge zone contains several small-scale thrusts which have disrupted the thin sandstone bands.

I should have included an object for scale in this view but forgot, sorry! The pale sandstone band in the central portion of the photo is about 4 cm thick.

Load structures on turbidite sandstones, Crooklets, near Bude, Cornwall

nobody@ipernity.com (Earthwatcher) — Thu, 17 May 2012 22:51:23 +0000

Earthwatcher has posted:

Turbidite sandstones in the Bude Formation (upper Carboniferous) display sedimentary structures which can be used to determine the 'way up' of the bedding. Here, the sandstones display small-scale slump or load structures on the basal surfaces, and some beds show 'fining up' on the grain size (indicated by gradual darkening of the bed).

These structures demonstrate that the beds here are the right way up, i.e. have not been completely inverted by the strong folding this area has undergone. The sequence shown here gets younger upwards and to the right.

On the limb of an anticline, near-vertically bedded turbidite sandstones in the Bude Formation (upper Carboniferous) display sedimentary structures which can be used to determine the 'way up' of the bedding. Here, the sandstones display small-scale slump or load structures on the basal surfaces, and some beds show 'fining up' on the grain size (indicated by gradual darkening of the bed).

These structures demonstrate that the vertical beds here get younger to the right.

This is a hover fly Eristalis tenax (a.k.a. a Drone fly) which is a superb example of insect mimicry. This is not a bee; it does not sting. It is feeding on a Buddleia bush in my garden.
