What reading level is Ore Deposits a Discussion Re Published From the Engineering And Mining Journal book?
To quickly assess the difficulty of the text, read a short excerpt:

Until within very recently some investigators have claimed that an original deposit of gold without quartz was an unobserved phenomenon. Mr. Spurr, as I understand him, maintains that the derivation of a gold-bearing vein uninterruptedly from a siliceous rock is not only a possibility, but is a plausible explana- tion for many of the occurrences in nature. He eliminates the break in the continuity of phenomena which is a neces- sary accompaniment to the formation of a vein in a previ- ously exi...sting fissure. Without taking up here the various definitions of a vein which have been advanced, I would suggest that Mr. Spurr has rather overlooked the physical side of the question in his desire to lay stress on the chemi- cal activity involved. If the occurrences to which he draws attention are quartz segregations, even though they contain sulphides of the metals, and are payably aurifer- ous, they constitute a very exceptional class of veins, ac- cording to my understanding of the term. Indeed, I ques- tion if they should be classed as veins at all.
