Abstract
I t is nearly fifty years since this mine first attracted the attention of mineralogists by the occurrence of haytorite (chalcedony pseudomorphous after datholite). Several papers on the mineral were contributed to the Philosophical Magazine*; and an account of the mine was given by Mr. J. T. Kingston†. His description deals with the beds seen in an open work, and is so full and clear that there would be little left to add were it not for the fact that a new adit-level has intersected the beds and exposed a new section. There are certain points in this section which I think are worthy of being recorded; besides which it is well to call attention to the fact that there is now a good opportunity of studying the mode of occurrence of a fine deposit of magnetite without the necessity of making a journey to Norway or Sweden. Haytor Mine is situated on the eastern borders of Dartmoor, about three quarters of a mile from the pile of granite rocks from which it derives its name. The iron-ore occurs in the form of thick beds of magnetite interstratified with altered shales and sandstones of Carboniferous age. Near the iron-ore the rock becomes highly charged with hornblende, and is sometimes apparently entirely made up of actinolite. Garnets, too, occur in great abundance in some places; and I also found a thin layer containing iron pyrites and what appears to be axinite. The secton seen near the end of the adit-level is shown
