From what I understand, the majority of monazite is located in the mountainous regions of North Korea, although the monazite itself is most often mined in stream and river "placers"<span style="font-size:14pt;"> that flow from those mountains. </span><span style="font-size:14pt;">Since much of my information was obtained from pre-war Japanese
geologists, I'm wondering how much of this geological information was available to the British and to the Americans during WWII.</span><span style="font-size:14pt;"> </span></div><div id="ecxyiv9317326685yui_3_13_0_ym1_8_1395228210317_59"><span style="font-size:14pt;"><br></span></div><div id="ecxyiv9317326685yui_3_13_0_ym1_8_1395228210317_59"><span style="font-size:14pt;">-- Bill Streifer</span></div><div class="ecxyiv9317326685yahoo_quoted" id="ecxyiv9317326685yui_3_13_0_ym1_8_1395228210317_71" style="display:block;"><div class="ecxyiv9317326685yui_3_13_0_ym1_1_1395228210317_33335" style="font-family:'times new roman', 'new york', times, serif;font-size:14pt;"><div class="ecxyiv9317326685yqt0505803014" id="ecxyiv9317326685yqtfd89128"> </div></div><div class="ecxyiv9317326685yqt0505803014" id="ecxyiv9317326685yqtfd18452"> </div></div><div class="ecxyiv9317326685yqt0505803014" id="ecxyiv9317326685yqtfd18614"> </div></div></div></div><style><!--
