It is the further aim that the data for each of the formations be as current as possi ble. Consequently, the emphasis has been placed on th e recent literature . Although this paper should not be viewed as a discussion of the historical development of each of the fo rmations, the original reference for each of the units is given . Also, in cases where the historical development of the formation has a direct bearing on present-day problems it is included in the discussion . A wide variety of published literature and unpublished reports , theses, and dissertations was con sul ted and several professional opin ions regarding specific problems were so licited . In recent years re search has been concentrated in the Klamath Mountains and the southern Coast Range and for these regions literature was volumi nous. -

Pickerill Volume 25, Number 2, August 1989 Article abstract The upper Middle Cambrian to early Late Cambrian King Square Formation, URI: https://id.erudit.org/iderudit/ageo25_2art03 Saint John Group, southern New Brunswick, is an approximately 380 m thick silicilastic sequence of interbedded fine-grained sandstones and siltstones and See table of contents shales. On the basis of sandstone to shale/siltstone ratios, bed thickness and characteristics, sedimentary structures and degree of bioturbation three lithofacies are recognized. These are facies KS1, thin bedded sandstone and Publisher(s) shale lithofacies; KS2, thick bedded sandstone lithofacies; and KS3, bioturbatcd shale and siltstone with interbedded sandstone lithofacies. These lithofacies Atlantic Geoscience Society are interpreted to havebeen deposited on a wave- and storm-influenced marine subtidal shelf. Facies KS 1 was deposited essentially below wave base ISSN though in its upper horizons, deposition may have occurred above storm wave base. Facies KS2 was essentially deposited in a shallower subtidal inner- to 0843-5561 (print) mid-shelf environment above storm wave base and facies KS3 initially above 1718-7885 (digital) and latterly below storm wave base. The exact nature of the currents responsible for transportation and deposition of the storm-related sandstones Explore this journal (geostrophic flows or turbidity currents) is impossible to determine and therefore palaeocurrent data must be interpreted with caution. The stratigraphic arrangement of the lithofacies, with facies KS1 being the oldest Cite this article and KS3 the youngest, suggests that the King Square Formation represents a regressive-transgressive sequence. -

Corcoran State Geologist FOREWORD This is the second in a series of pu blications of the State of Oregon Department of Geology and Mi neral Industries that discusses the petroleum potential in various parts of Oregon . The first report, published in 1963, covered part of the Snake River basin along th e eastern border of the state near Vale and Ontar io, where several test wells encou ntered large bu t discontinuous "shows" of gas. The present report is concerned with northwestern Oregon, particularly th e lower Columbia and Wi llamette basi ns . The northwestern part of Oregon has been an area of petroleum exploration for more than 40 years, but most of th e important dri lling activity has been confined to two brief periods -- the middle 1940's dur ing and shortly after World War II and the late 1950's and early 1960's , resulting from the gas and oi I showings in the Barr No . 1 wel l near Lebanon . Although no commercial production developed after th is explorational effort, the work has shown that th ick sections of marine rocks exist in this region and that in some areas porous and permeable sands are present . -
