1 GRANNY A data bank of chemical analyses of Laramide and younger high-silica rhyolites and granites from Colorado and north-central New Wexico

ABSTRACT

GRANNY is a data bank containing information on 507 chemically analyzed taramide or younger high-silica rhyolites and granites from Colorado and north-central Ney Mexico* The data were compiled from both published and unpublished sources* The data bank is designed to aid in the recognition of igneous rocks with a high exploration potential for the discovery of molybdenu* (and other lithophile element) deposits. Information on source reference, geographic location* age* mineralogic and petrologic characteristics* major constituent analyses* and trace element analyses for each sample are given. The data bank is available in two formats: (1> paper- or microfiche- hardcopy, and (2) fixed format computer readable magnetic tape. INTRODUCTION

GRANNY is a computer-readable data bank consisting of descriptive and chemical data for 507 rock specimens for which major constituent chemical analyses are available* The analyses were largely compiled from published works and theses* available either on microfilm or through inter- library loan services* Several colleagues made unpublished chemical analyses available to us t and these* together with our own unpublished analyses, were also included in the data bank The three 1/ granite (or Climax-type) molybdeni te deposits which are currently being mined in the United States occur within the area of our compilation. The source rocks for these deposits are high-silica low- calcium rhyolites and granites (Mutschler and others* 1981; yhite and others* 1981). Our compilation began as an attempt to assemble all the available petrochemical data for these deposits* and for the many granite molybdenite system prospects in Colorado* We then decided to broaden the data bank to include all Laramide and younger high-silica rhyolites and granites in Colorado for which chemical data were available* Our aim was to produce a data bank that would help in the development of "chemical fingerprints" for the recognition of high-silica rhyolites and granites with a high exploration potential for the discovery of Wo (and other lithophile elements such as Be* Sn» U* and W) deposits in Colorado. For inclusion in the data bank we have defined high- silica rhyolites and granites as those igneous rocks containing at least 70*0 weight percent Si02* We have also included 33 analyses with less than 70*0 weight percent Si02 where those analyses represent rocks which are clearly related to granite molybdenite deposits or prospects* We have tried to structure GRANNY so that it can be interfaced with other petrochemical data banks such as CLAIR (Le Waitre, 1973), IGBA (Chayes and Wutschler, 1978), PETROS (Wutschler and others, 1981)* and RASS (U. S. Geological Survey, 1983). This* we hope, will allow the petrologist and explorationist to rapidly test models based on the Colorado data in other areas.

DESCRIPTION OF GRANNY

GRANNY 1s available in two formats: (1) hardcopy* either as paper- or microfiche-copy of computer printout; and (2) computer-readable magnetic tape. The same information is contained in both formats except that on the hardcopy version some information which is stored in code on the tape version is printed as the corresponding English literals. For example* the mineral name "quartz" is stored on the tape version as , but is printed out as "QUARTZ" on the hardcopy. The analyses in the hardcopy version of GRANNY are arranged by major groups and by secondary groups as explained below* Major groups are arranged in alphabetic order and secondary groups for each major group are arranged in the order listed on Table 1. On the tape version of GRANNY analyses are arranged sequentially by record number (see below), in the order in which they were entered into the data bank. Tape characteristics are listed on page 35. The following two sections are addressed to different audiences. The section* "Variable descriptions" tells the petrologist-user what information is stored in GRANNY. The section "Tape description* data formats* coding form* and program listings" is directed to computer programmers and data managers who will be responsible for loading the data bank into a computer and interfacing it with system- or user-supplied software. Variable descriptions

Values for up to 106 variables may be stored for each analyzed specimen. Each analysis must Have values for the variables AUTHOR, DATE, MAJOR GROUP, ROCK CODE, RECORD NUMBER, and at least eight of the MAJOR CONSTITUENTS: Si02, A1203, Fe203, FeO, MgO, CaO, NaZO, K20, H20, H20-, TH20, Ti02, P205, and MnO. The variables are described below and are listed on Table 5. AUTHOR: Surname of author. Multiple authors are indicated by a plus sign (*) following the senior author's name. Complete citations for all references and unpublished data are given in Table 1 . DATE: Year of publication or year of inclusion in data bank for unpublished analyses* WAJOR GROUP: The analytical data are divided into 15 major groups which represent geographic areas* A three character alphabetic code is used for each major group* Table 1 contains a listing of the major group codes. The areas represented by the major group codes are shown on Figure 1.

SECONDARY GROUP: Major groups may be subdivided into secondary groups (abbreviated SECOND GROUP on the printout)* Secondary groups represent geographic location* or stratigraphic unit subdivisions* A two- to four-character alphabetic code is used to designate each secondary group* These codes are listed in Table 1. Even if a major group is divided into secondary groups not all analyses in that major croup need have secondary group codes. On the printout analyses not assigned to a secondary group are listed last under each major group. i | »| |M| 1\ I "N S-il-'l- XI I ' N /
