The work includes generalized geologic mapping correlated with map units, explanatory legends for imagery interpretation, and quantitative visual summaries such as histograms of lineament trends and relative intensities. It documents observed and classified lineament features, discusses inferred geologic structures and deposits, and provides correlations to support interpretation across Jurassic to Tertiary sequences.","DEPARTMENT OF THE INTERIORUNITED STATES GEOLOGICAL SURVEYBase fror USGS 1:250,000 topo series:XETEH[KAN,1955;PRINCE RUPERT,1959,AA5A-LANADA.  \nFigure 3.--Histagran of trends and cuul ative lengths of lineamentsobserved on Landsat imogcry of the ketchikas and Prince Rupertquadrzngles,  \nOPEN F'lLE REPORT  \n78-73 K  \nFolio of the Ketchikan and Prince Aupert Quadrangles,Alaska  \nSHEE丁1 CF 28TEELE AND ALBERT--INTERPRETAYION OF LANDSAT IMAGERY  \nCORRELATION OF MAP UNITS  \n[Geologlc map generalized from Berg and others(19731]  \n□UATERNAFY(T.AND TERT1ARYTnsTep  \nEhTIART LTKp3 CRETACEOUsKJupKJ8买Jva+TEAAS91ChRTRIA3510  \nMESozDIC 0NMzFzM2P险uFALEDZDICPz8  \nPALE0z0iCPZY  \nORPZpSHuriaOLDERPzECuLMU8tICATEC DEPOS1T5,IBDTWTTED 10u2 ternry}QTeLCAN]C ROCKS fCnatarary and TartarylTxpBC]YTDFE MrCCFW PLITIC s知CKSTopIBMD1WTDED EDCEHE PLLTIIMIC sCCSTKpBC1V[CED TEKTIARY08 [BFTECF3LS PLUTCNIC RULKS  \nDESCRIPT1ON OF MAP LNITS  \nGWMM 1SLMF FPATI0N AHD MAED CCRRELATIVE SDC5(Lurer tretacess ur lkper durissi)Jus1trsnafie ane nther plntentc rocksKJsPetasefrartary n.cks  \nK,Je  \nPetavnlcanit recks3b:TEAAS CREEK CBANIETnRTTE (Jurass10 or Triass1c)JhvsVFTAMCFPHOSED VnLLAHIC    SEU1MENIARY sDCS durassic or Trisstit!zHETAMCRPHOGED SEDEPFHT4RY AND wLEELC RUCK Lpper Triessic]pPA5AGHFISS AHD QMPH-[BELITE{MesDzu1t br Paleuzuit]的物uVFTAME=HIC RCKS,IMLV1ED〔Pesuzo1t cr Paleozoic〕  \n25HFTAMLE7HOSEU SEUJPEHTARY AND PMCR Y0LCANI BOCKS(Niddle ne uer Pa1*zsle)险FFLSIC.FETANILGNIC 8CCRS(Patoozcic or oldem'PpLITCMIC ROCK5,CHLEFLY TFUMBJEMLTE (Silurian ar elder}z%EIAHDR=R0SL SEDIKLHTARY AKDy0LC4HC RCCK515E1urian ir cldr  \n5NEDLS  \nContect,Appraxfrataiy lecatad;dotted stere zencealed--…Highangle fault.Lashed uhara inferred;dotted where fcrcesledTherust fzult.Dashed where concealed,i=ferred,or assiredSavteeth on uper plate  \nEXPLANATION OF IMAGERY INTERPRETATION  \nWELL-DEFINED LINEAMENT.  \nCIRCULAR OB ARCUATE FEATURE.  \nMODERATELY DEFINED LINEAMENT.  \nCIRCULAR OR ARCUA TE FEATURE,  \nPOORLY DEFINED LINEAMENT.  \nCIRCULAR OR ABCUATE FEATURE.  \nIRON-OXIDE COLORED AREAS  \nUiscass la  \nIe gin in tie nirea₁resnume M   nt rf te keLhikan znd rinoe up arales,LartgJran)1c nla=m Etrn talhit e欧ed to that uinere2T   (E¹1icE:   othere,  \nbeferroes rit二  \nAite、n.A0:                    26,sie:5Be-a.                           fEII₁m+、L,BrsH.C,ard K₂x1.5sn,a,Mpr ta:le dearibs est211 (erus ard s1ete旧网-91|(part 73-70.5C8e 1;255,14.  \nKntt,1D.,au Ellitt,R.L.,15,Fnu lysis uf ro.ad shree rediest caplr ta Priroa hpert  \n①ran Ie,La   a55!1.5.G1igi1tal Sty pM1-f ile Yrt 12,9:1775,x pas of ro   Te.frra ts Futinika   rengls,soutknten A aŁ:U.S.Golagia)5Jr Cren-P1le rsjart 8-L5m,L6207.  \nU.5.Geelos iral Sarng,197?,iercasjrtle ne at zhe echita,rince Rupwt,  rotr  n Cagi让ed-gle.61aska;1.5.Gtl0qica Survey pen-P11epet 77-99,cl:1:250,002.  \nThis rapart.is prelixinary anl has  \nconfDriy with Gc□lpgieal Suryey  \nFigure 4.--Histogram of trends nd relatfve intens fties of_1irea-Per ts Tess thar 10 kn lorc a dteniiner hy use of a diffracticngrating an Landsat tnagery of the Ketch 1kan and Prtnce Rupertquadrangles.Relative intensities are subjective.  \nBY","cbCaiqisy2IiG688","https://ap.wps.com/l/cbCaiqisy2IiG688","pdf",3589133,1,"English","en",105,"# Figure 3.--Histogram of trends and cumulative lengths of lineaments observed on Landsat imagery\n## Open-file report\n# Description of map units\n## Deposits and volcanic rocks\n## Sedimentary rocks\n# Explanation of imagery interpretation\n## Lineament feature classes\n# Figure 4.--Histogram of trends and relative intensities","[{\"question\":\"What geographic area does the report cover?\",\"answer\":\"The report focuses on the Ketchikan and Prince Rupert quadrangles in Alaska.\"},{\"question\":\"What type of data is analyzed in the report?\",\"answer\":\"The study interprets Landsat imagery and emphasizes mapped lineaments and related geologic features.\"},{\"question\":\"How are lineament features categorized?\",\"answer\":\"Lineaments are classified by definition quality and geometry, including well-defined, moderately defined, poorly defined lineaments, and circular or arcuate features, along with iron-oxide colored areas.\"}]","Folio of the Ketchikan and Prince Rupert Quadrangles, Alaska -
