INTRODUCTION

In this first stage of rescavch on the use of the data obtained through

Landsat satellites for [lie invenLory of natural rresolarecs, the first e%-

periences on gcology aW edaphology have t)c un obtained.

GENERAL INPOlIMA"I"ION' ON '1711l, AREA UfJDLI:Z S"PUDY

The area under study is Located beLwer.n parallels 20° 00' N and 22°

00' and between the Meridians 100" 15" W anxl 102°_00" W. However, in

this first stage only the area of one image, nr central coordinaLes

2I.° 45' N and 7.00° 2.0" VV, has been studied. ' 1ic image was taken by

the satellite on March 2E, 1076, a-d hours Lhe identification number

E 2431-16231. It is covered by 'I t"U'l"I.AAL chanty each of which

embraces Borne 1000 l;xr12.

The climate of the ]lower part., of the arek is he y to warra semiarid

with mcan annual temperatur~c hrl m,,aLn 1B Lm'] 22"C and nican annual

precipitation of 400-500 mm. I:n its mountaiu,ki . Harts, ttxc climate is

Lcnrperate serniar.ld with mean annual Lempera f tlPes of J. 0-1.8 °C and

mean annual precipitation of 500-600 mm.

®r p00^Qrr^ ^Yi 3

Geologically, the area covered by the image is made up for llnc greater part of Tertiary volcanic rocks, mainly rhyolRes with some basalt ranges. The flat areas are covered by Quaternary alluvia excepting small. areas of Quaternary basaltic lavas in the eastern

part. In [lie north sector of the image there arr, two bands of sedi- s mendavy rocks. The eastern one, in long and narrow folds, irr made up of limestones and shales as well as calcareous shales interbedded with Jayers of calcareous sandstones. In the one ork the western side of the iarjage, these same rocks form broad ranges, reiimants of overthrusts with a corniplex carstic topoga^aphy. The schists in the southvmsL corner of Llic image are predominantly meta-vol.canics. The green schists in the southwest corner of the image are predominantly nicta-vol.ca )-jes in greed schist faraies. (Tl1e above is vcrba;. information given by Ing. Alejandro Bello 7jarrada6 and th.e Carta 0-011 lo'gica de la Republica liexi.cana),

T^-e geological and edaphol.ogi.cal inter:-pvcLation was carried oW with the use of the 12S Alini-Addeol Color Viewer at an approairnnetu scale of 1:500 000. Various trials with bands and fillers were run until j - was doci.ded, hi the geological studies, to uLi.lizo bands, 4, 5 green and 7 (d. ^ wi houL filter, 5 with filter aijd -7 with red filter) -and, ^in the edaphol.ogical studies, bands 4, 5 and 7 silPi. blue, green and h

reel filters respectivoly, though contacts were also checked on the various bands without filters. lurid G was not used clue to mal func.tioningt of Clio apparatus. Contacts were traced with [lack ink on transparent acetate film. The use of a hand lens (4 dioptri.es) was found help ful for both types of study. The geological studies sought to obtain: 1. The drainage of the area as revealed by the image. 2. The deliruitation of the principan lat.es of the area. 3. The principal w-id secondary alignruenls (faractures, faults, etc.) - found in the area.

4. The lithology of the area, clt si iod in broad units The edaphologi.cal studies pursued the dolineation of broad units of

soil groups in the area. i A selection and compilation of gecflogicui studies basil on images as well as other geological stud i.-: ca' the ai" a y:',as carried out and

CONGIASIONS. In the present stale of the investigation we are ablee to coi-Sivin the fact pointed out by other workers that satellite images represent a very use ful toel in [lie claboration of regional maps of geological or eclapho'r, q cal nature. Major structural features, drainage patterns and lithologi- cal units as well as soil associations may be disting,uited and repre. . in Led iii inaps drawn up at a low cost. ^ A
