232 GEOLOGICAL SURVEY OF THE TEERITOEIES. 



47. Porpliyritic volcanic roct, 20 feet. 



48. Brovvuisb-gray areuaceous limestone, 15 feet. 



49. Blue lamiuated limestoue, 15 feet. 



50. Sbales, 5 feet. 



51. Porphyritic volcanic rock, 20 feet. 



52. Bine laminated limestones, 6 feet. 



53. BInisli-gray limestone, fossiliferous, 10 feet. 



54. Volcanic rock, 8 feet. 



55. Blue shaly limestoue, 15 feet. 



56. Sandstone, 10 feet. 



57. Blue slialy limestone, 15 feet. 



58. Sandstone, 6 feet. 



59. Bluish black limestone, 5 feet. 



60. Brownish quartzitic sandstone, 21 feet. 



61. Bluish black limestone, 11 feet. 



62. Sandstone, light colored and soft above, becoming darker and quartz- 



itic as we go down, 10 feet. 



63. White laminated volcanic rock, 17 feet. 



64. Indistinct outcrops of a black shaly limestone, 12 feet. 



65. White quartzite of a rusty color on weathered surfaces. Just 



above it there are indications of bluish limestone, probably a con- 

 tinuation of bed 64, 75 feet. 



66. A very dark-blue limestone, weathering black crystalline, and con- 



taining nests of calcite distributed through it, 8 feet. 

 h.67. Light colored lamiuated porphyritic volcanic rock, very similar to 

 No. 63, about 10 to 20 feet. 



68. Dark bluish-black limestone, very irregular in structure, especially 



near the top ; at top is pink on weathered surfaces, 60 feet. 



69. Sandstone and limestone conglomerate, .10 feet. 



70. Dark-blue limestone, 2 feet. 



71. Rusty-brown quartzite, 2 feet. 



72. Blue limestone, 50 feet. 



73. Light-gray quartzite, 4 feet. 



74. Light- blue limestone, with irregular cross-fracture weathering of a 



lighter color, for the most part fine grained, becoming coarse in 

 some places. In the upper part it becomes laminated and some- 

 what darker. On weathered surfaces there are crinoidal frag- 

 ments. Thickness estimated, 10-15 feet. 



75. Light brownish quartzite, passing into sandstonte near the top ; a 



few feet from the bottom there is a layer, a few inches in thick- 

 ness, of greenish sandstone, 20 feet. 



76. Magnesian limestone, light colored, with seams of dolomite. The 



beds become darker from the bottom up ; 50 feet. 



77. Light-bluish magnesian limestone, weathering of a yellowish color, 



becoming siliceous as we go down, 15 feet. 



78. Brown quartzite, 10 feet. 



79. Laminated sandstones,general color a pinkish gray; about half way 



down there is a layer of shales. The lamination is most distinct 

 in the lower part of the bed, the laminae having a red coating, 15 

 feet. 



80. Massive gray sandstone, 10 feet. 



81. Pinkish-gray sandstone, laminated, laminae 1 to 3 inches in thickness, 



with green coatings between, 10 feet. 



82. Light-gray laminated sandstone, somewhat shaly in places, laminae 



from 1 to 3 inches in thickness, 6 feet.
