ON THE OCCURRENCE OF FOSSILIFEROUS 
HAEMATITE NODULES IN THE PERMIAN BRECCIAS 
IN LEICESTERSHIRE, 
TOGETHER WITH SOME ACCOUNT OF THEIR ECONOMIC 
VALUE, &c. 
BY W. S. GRESLEY, F.G.S. 
The following observations have been written with a 
twofold view : to make known certain features possessed by 
some red haematite* nodules occurring in the neighbourhood 
of Ashby-de-la-Zouch, in Leicestershire; and to interest 
others who have a geological turn of mind, in possibly 
taking up the questions herein noticed in a more scientific 
and searching manner than has been possible to the author. 
I propose to divide the paper into the following heads :— 
Description of Plate I. 
No. 1.—Fragment of a nodule of red haematite showing a peculiar 
mammillated or “ eyed” agate-like structure. Natural size. 
No. 2.—A nodule or “pebble” of very hard and compact red 
haematite. Natural size. 
No. 3.—Part of a nodule of red haematite exhibiting concretionary 
structure. Natural size. 
No. 4.—Small ditto ditto. Natural size. 
No. 5.—A striated nodule or “ pebble” of haematite. Natural size. 
No. G.—A fragment of compact haematite, showing “ eyed” structure. 
No. 7.—A small pebble of iron-ore. Natural size. 
No. 8.—A small nodule of haematite. Natural size. 
No. 9.—Fragment of haematite (magnetite) showing columnar 
structure. Natural size. 
No. 10.—Haematite, with leaflet of Neuropteris gigantea. Natural size. 
No. 11.—One-half of a nodule of raddle, containing Anthracosia. 
Natural size. 
No. 12.—Fragment of compact red haematite, similar to vein iron-ore. 
No. 13.—Nodule of iron-ore showing concretionary (?) structure. 
Natural size. 
No. 14.—Hard red haematite, containing Asterophyllites foliosa (?) and 
showing botryoidal structure. Natural size. 
No. 15.—Fragment of limonite containing leaflet of Neuropteris 
gigantea. Natural size. 
* Often magnetite, and occasionally compact limonite.
