Research on this deposit is still blank. Basedon the geologicalsurvey on thisdeposit, its ore-controlling factors and thegeologica-l geochem ical characteristics are studied,and its causes are analyzed aswel.l In combination w ith nearly one-year researches, themineralization and ore-controllingfactors and oreprospecting direction in future forLongwanggoum ine area ofQ inshanGoldM inearepointed out. This resultprovides a reference forfurtherstudy on the deposit, and also accumulates new information for the regionalmetallogenic the-ory ofZhen-xun basis.K eywordsnull Characteristics of thedeposit, Ore-control factor, Ore prospecting direction1nullu×¹É+˜“ש¹Ê¿U4ð vêU4,©¹§sK¿“½ðû“,2§sK¿½ B,φ?âµ2öb©¹¹B_2laêͿ륶™©¹,©¹=?âV½=@žC©@ õÃæb©¹™îÄVñÏ,©¹=†2_]3?â,]H{'†ö£AîFsbª/[Íê_`âeŸ¹ö,_Q­b“ש¹=,Á €ö1sƒÁ4¯T_|2§,î2 €{b{[ÁCö-m4Á €5¹ö,Z_µ=û0Á €;2{ö1µdEÁ €©(m1)b“ש¹=æûuÁ €î €¹Éßa¸€û"a e €/a €5¹É+˜#Á¥®iÿa€5¹oÄЩZë,û µ±%Ï™˜Á €¥Bî+˜bt+˜¿“ש¹=Ùs 5˜Á €,­¿{“¶#2 €{sÁ, µ×1¥ ؂„CLil[ 1]b2null €u¹É+˜C¦Á €u]¹ªe†,ö1µC©"dô ÚÙF„F"/d¸Š§Fbô ÚÙFö1null117null¹Bça0çsäéÁÉðûª;¸Š§Fö1¹B*ϨªCªëFH{Y ìçûûª, †C‘äÁÉðûb€u=/?â, EW_¥F2:,œñ €u,i €uS¶=® €,7 €u“= AZ³F(m2Ï¥null| €),iµ±ЍM €ÄbÍSN_¥Q)ÐF2Œø)™î¶€¥5 €8,O €FÖÊ Úb†sÍSN_Q)¹î €ª, €8åÊT¨(m2)b€u=]¥û8ö1¹F‡úÉû8,sƒ €u¥Hb¸ €¶ûö1¹¸Š§F'çäϨª…Ö± ìçû#ô ÚÙFçäa0çsäéÉðûÐéÁÉðûb €8?â)¶û €ÄKMø×,ö1KMµAÄaÛM €ÄaM ‡ûÄaMÖ÷Ä©b €5îy¹µ0÷@8•Ð¥Ï-®Ñ˜£A €5b3nullî €yÍs3. 1nullûŸyÍC¦ €uv” €8sƒ/Fd¸Š§F»Bª(C1 j1 ),¶ûûŸ¹Ï¨ªCªëFH{v vY ìçû,ûÉ B, ìY, æ¿ €AŒ},yN €(Ä)8A , 3ñ v¥ €8 (Á¿NçûÏ;䆹/Fd¸Š§F»=ª(C1 j2),[CÉû¹ö,¸†¹C©dô ÚÙF(D3 j2),¹B*cÁ Ú¥[CéÁɹö,¶cÉaAÉ„ÛM €²‚¥$û®ªFîbƒ2*¹ª (‚ æ¿ €AŒ},ŒT¹ä(¸)ðH, VT¹¹oÄÐp €A¶"žz¥{ ¤rTb†s% €85sƒéÁÉH{v vAÄâ É% ìçû( C1 j4)åÞ{ÏbC¦9Á3ñv˜ €,Q) €8¹l˜ €8,Osƒ"ÏbYLªü,C¦Á€5BçµBñ4î €þÉ¥Sc €ûFbùîVü,C©dô ÚÙFcÁß´¹1. 1 null10- 9,7Í €¶ûÁc15 null10- 9~ 78 null10- 9­W,ùÚ¿¹ TAu¥ X ˜ X´,ªü¾*¹ª €u“¶,Á$ÄÆî €£A,¹î €ùÁ¥¶"4þÉ Ÿ÷,™î €÷ªb3. 2null/yÍC¦ €uò €5 €8¥Zƒ+˜#L=ýTÏ e €/'¥ùî£ü,sƒ/Fd¹É8Ï¥Á €5øìs €u/¥ eÅb €u/ö1µNE_¥F15, F16, F17©„ÍWE_¥F2,OF2¸ €bNE_ž¿ê_3î,ipWE_bNE_¹¸ €/, eÅ €8¥sƒ™ÿ,ÏNE_ÐF2ø†)ªª™îv˜5 €8b’/µæ¿iiH,9 V[3îl €8b €ª98Á ×ç, †`_„,‚†"/† €cÁ¥ÚÖÊŸ, V¹/B„·UsÁ4Z_b4nulls €+˜s4. 1nullÈíÍ+˜C¦ €u €F ˘¹MÁ €F,V1MÁ €F#Í €¶ûðûaéûaçû¥ÄÐîss²TbVV1 V[ A,V¶ûž €8, SiO2, FeO,Al2O3¥c9Ú,7CaO, K2O¥c†®,Vü¶ûÐî €@8?3 320 2. 1V+ L 8‚?515% - 6. 1 216. 7 9. 8null nullÿ:®RÄ¹É €Áùîî©kbÁ €î €@8^[H2O¹ö¥@8,7'†@85^[CO2©8Fs¹ö¥@8[ 4]b7¾ €5V /(V + L) ³, è €u[êF2ªZ³F?âua» g[åÞ{©,¹VX?C €ÄL쥹u,V。
